The change event doesn't actual change when you change the value; it only fires when the control loses focus.

Even on the Telerik Demo, it only updates the log box when you click off of the control.

How do I make it fire when I am typing in the control itself?

Hello Tracy,

The behavior you described is by-design, but if you would like to use the change event every time you type, one approach you can use is trigger the change event on the jQuery keydown event.
$(document).ready(function() {
  function onChange() {
    console.log("changed!");
  }
 
  $("#maskedtextbox").kendoMaskedTextBox({
    mask: "(999) 000-0000",
    change: onChange
  });
   
  $("#maskedtextbox").keydown(function() {
    var maskedTextBox = $("#maskedtextbox").data("kendoMaskedTextBox");
    maskedTextBox.trigger('change');
  })
 
});

For clarification, please take a look at this Kendo UI Dojo by Progress which demonstrates the approach above.

Please be aware, however, there are some limitations to using the keydown event using mobile editing.  

I hope this helps!

I actually found it better to use the keyup jquery event because it captures the backspace/delete key as well.

Thanks for the update!
