title: Listening for dataChange event in AdvancedDataGrid
body: <p>This is my code: </p>
  
  <pre><code>&lt;controls:AdvancedDataGrid id="adg" dataChange="adg_dataChangeHandler(event)"&gt;
        &lt;!-- other stuff goes here --&gt;
  &lt;/controls:AdvancedDataGrid&gt;
  </code></pre>
  
  <p>and in my ActionScript code:</p>
  
  <pre><code>protected function adg_dataChangeHandler(event:FlexEvent):void
  {
    trace(1);
  }
  </code></pre>
  
  <p>When I edit a cell in advancedDataGrid (making the columns editable of course) it never dispatches an event. Or, in other words, my function is never called. How can I fix this?</p>
