title: jQuery change event not firing for input field
body: <p>I'm trying to remove an alert on a form when a user fixes an empty field.
  My generalized code works for all input elements where the user has to type in the field, but my input that has a popup calendar does not fire the "change" event if the date is placed in the field by the system.  I thought the change event fired when the field lost its focus?</p>
  
  <pre><code>        $("#my_input").change(function() {
              $(".StatusBox").html("");
              $(this).unbind("change");
          });
  </code></pre>
  
  <p>I have another piece of code that runs after this and changes the input field(user clicking on a calendar date and therefore updating the input). Shouldn't that fire the change event?</p>
