                    tip.setTitle('name');
                    tip.update('Count: ');
                }
            },
            fieldStyle: fieldStyle
        });
        return nameField;
    }

As can be seen in the textfield docs, fields do not have a way to add a tooltip to their configuration, so you would have to create the tooltip manually.

If you look at the docs for Ext.tip.ToolTip how to do that, you may find a small example, where you just have to change the target as per the target configuration description:

var tip = Ext.create('Ext.tip.ToolTip', {
    target: nameField.getEl(),
    html: 'Press this button to clear the form'
});

Above answer is correct. Here is example of generic function which you write once and use wherever you required in project by using using attributes.

addToolTip : function (id, msg) {
    new Ext.ToolTip({
            target : id,
            dismissDelay : 0,
            anchor : 'right',
            html : msg
        });
};
