title: Label dataChange event not getting fired
body: <pre><code>&lt;mx:Label id="myLabel" dataChange="{trace('changed!!');}"  /&gt;
  </code></pre>
  
  <p>I change the text in the above label:</p>
  
  <pre><code>myLabel.text = "new text";
  </code></pre>
  
  <p>But nothing is traced as it's supposed to. </p>
  
  <p>Am I using a wrong event? I thought <strong>dataChange</strong> is fired when text in the label is changed. </p>
