title: Fire onchange event for TextBox when readonly is true
body: <p>I am trying to have some functionality on change of a textbox which is readonly. 
  But when I am trying to update the textbox using javascript, the change event is not firing for the textbox.</p>
  
  <pre><code>&lt;script type="text/javascript"&gt;
          $(document).ready(function () {
              $('input[id$=_txtTest]').bind("change", function () {
                  alert("test");
              });
                          });
          function ChangeText() {
              $('input[id$=_txtTest]').val('hello');
           }
      &lt;/script&gt;
  </code></pre>
  
  <p>I am calling ChangeText method on click of a button. But it is not firing the textchange event for the textbox.</p>
  
  <p>Can anybody tell me what is wrong here?</p>
