Multiple input boxes - alertifyjs / Jquery

I am trying to create a prompt dialog box using alertifyjs that has multiple input boxes. I have managed to create the dialog box to show the multiple boxes but I cant seem to make a reference to the inputs that user provides.

I want to write if statement that carries out action based on user input when they press OK. However, the OK button doesnt seem to be working and also the if-statements don't work as well. I am not sure what I might be doing wrong, can someone please help me.

Below is my code:

<!DOCTYPE html>
<html>
<head>
     <link rel="stylesheet" href="//cdn.jsdelivr.net/npm/alertifyjs@1.11.1/build/css/alertify.min.css"/>
    <link rel="stylesheet" href="//cdn.jsdelivr.net/npm/alertifyjs@1.11.1/build/css/themes/bootstrap.min.css"/>
    <script src="//cdn.jsdelivr.net/npm/alertifyjs@1.11.1/build/alertify.min.js"></script>


</head>

<body> 

<div style="display:none;" >
    <div id="dlgContent">
        <p> Enter Value One </p>
        <input class="ajs-input" id="inpOne" type="text" value="Input One Default Value"/> 

        <p> Enter Value Two </p>
        <input class="ajs-input" id="inpTwo" type="text" value="Input two default Value"/> 

    </div>
</div>

<!-- the script  -->

<script>
  var dlgContentHTML = $('#dlgContent').html();

$('#dlgContent').html(""); 
alertify.confirm(dlgContentHTML).set('onok', function(closeevent, value) { 
                    var inpOneVal = $('#inpOne').val();
                    var inpTwoVal = $('#inpTwo').val();
                    updateListItems(inpOneVal,inpTwoVal);   
                  if (inpOneVal == "test" && inpTwoVal == "test") {
                      alertify.success('Successful');
                   } else {
                      alertify.error('Wrong')

                    }
                }).set('title',"Update");
 </script>

</body>   
</html>

In your script you call a function named updateListItems(inpOneVal,inpTwoVal);

As that function is not declared anywhere, it errors, so with that temporarily commented out, it works.
