How to add Grid with two rows and a content to a B

Question

I created button in a XAML which contains image and text, I used Grid inside a button for that. Here is my XAML code:

<Button x:Name="btnAddNewItem"
                    Grid.Column="0" Grid.Row="0"
                    FontSize="15"
                    BorderThickness="1.5"
                    HorizontalContentAlignment="Center"
                    VerticalContentAlignment="Center"
                    Foreground="White"
                    Background="White"
                    BorderBrush="#0091EA" Margin="5,0,0,0" Height="90" Width="90">
                    <Button.Template>
                        <ControlTemplate TargetType="{x:Type Button}">
                            <Border BorderThickness="{TemplateBinding BorderThickness}"
                    BorderBrush="{TemplateBinding BorderBrush}"
                    Background="{TemplateBinding Background}">
                                <ContentPresenter HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}"
                                  VerticalAlignment="{TemplateBinding VerticalContentAlignment}" />
                            </Border>
                        </ControlTemplate>
                    </Button.Template>
        <Grid>
         <Grid.RowDefinitions>
            <RowDefinition Height="80*">
            <RowDefinition Height="20*"/>
        </Grid.RowDefinitions>
            <Image Source="/MyProject.Wpf;component/Icons/customer-icon.png" Margin="10" Grid.Row="0" Width="Auto"/>
            <TextBlock Foreground="Black" Margin="0,0,0,3" Grid.Row="1" VerticalAlignment="Center" HorizontalAlignment="Center" >Customer</TextBlock>
        </Grid>
                    </Button>

Here is screenshoot of my button, and how that acctualy looks when my app is runned:

As you can see guys, there are image and text inside of my button.

Now I'm trying to make same-look button but from code behind and I achieved this (here is image):

It's almost the same button but It's missing image+text which should be placed in Grid ..

Here is my code :

 Image imgControl = new Image(); // place where I should keep my icon
 TextBlock text = new TextBlock(); // place where should be text below my icon

 imgControl.Source = new ImageSourceConverter().ConvertFromString(uriSource) as ImageSource;
 text.Text = "Test text";

            string uriSource = new Uri(@"C:\Projects\MyProject.Wpf\Icons\customer-icon.png", UriKind.Relative).ToString();

            SolidColorBrush mySolidColorBrush = new SolidColorBrush();
            mySolidColorBrush = (SolidColorBrush)(new BrushConverter().ConvertFrom("#0091EA"));

            Button a = new Button();

            a.BorderThickness = new Thickness(1);
            a.Background = Brushes.Transparent;
            a.Foreground = new SolidColorBrush(Colors.Black);
            a.BorderBrush = mySolidColorBrush;
            a.Width  = 90;
            a.Height = 90;
            a.Style = Application.Current.Resources["MyButtonStyle"] as Style;

            Grid grid1=new Grid(); // I'm trying to add grid1 with two rows where I should place image and text, [row 0] for image, [row 1] for text
            RowDefinition rowImage = new RowDefinition(); //creating row one
            RowDefinition rowTitle = new RowDefinition(); //creating row two

            rowImage.Height = new GridLength(8.0, GridUnitType.Star); //Image will take 80% of space
            rowTitle.Height = new GridLength(2.0, GridUnitType.Star); //Text will take 20% of space

            grid1.RowDefinitions.Add(rowImage); //Adding image to row
            grid1.RowDefinitions.Add(rowTitle); //Adding text to row

            Grid.SetRow(imgControl, 0);
            Grid.SetRow(text, 1);

            a.Content = grid1;

As you can see, there is no image, neither text placed in my button, even if it looks like I added them to a grid which is added to my button.

So I guess I did something wrong with adding grid to a button..

Thanks guys, Cheers

EDIT FOR Ed:

switch (buttonPurpose)
            {
                case SettingsSubmenuItemEnum.Test:
                    {
                        button.HasIcon = true;
                        button.Icon = Controls.Enumerations.IconType.Other;
                        button.Click += EH_testButton_Click;
                        button.IconAlignHorizontal = HorizontalAlignment.Left;
                        button.TextAlignHorizontal = HorizontalAlignment.Right;
                        break;
                    }

                case SettingsSubmenuItemEnum.Groups:
                    {
                        if (!OperatorController.HasOperatorAccess(currentOperator)
                            return;

                        button.HasIcon = true;
                        button.Icon = Controls.Enumerations.IconType.Grupe;
                        button.Click += EH_SubmenuButtonClickGrupePromet;
                        button.IconAlignHorizontal = HorizontalAlignment.Left;
                        button.TextAlignHorizontal = HorizontalAlignment.Right;
                        break;
                    }

                case SettingsSubmenuItemEnum.Cities:
                    {
                        if (!OperatorController.HasOperatorPristup(currentOperator))
                            return;

                        button.HasIcon = true;
                        button.Icon = Controls.Enumerations.IconType.Other;
                        button.Click += EH_MjestaClick;
                        button.IconAlignHorizontal = HorizontalAlignment.Left;
                        button.TextAlignHorizontal = HorizontalAlignment.Right;
                        break;
                    }

 spContentSubmenu.Children.Add(button);
}
}

In code above I'm checking which button user clicked and by that I'm showing to him corresponding buttons..

variable buttonpurpose is SettingsSubmenuItemEnum type

You need to add the Image and the TextBlock to the Grid's Children collection:

...
Grid.SetRow(imgControl, 0);
Grid.SetRow(text, 1);

//ADD:
grid1.Children.Add(imgControl);
grid1.Children.Add(text);

a.Content = grid1;
