title: Flex AS3 - Creating a dynamic property, and then binding a control to it
body: <p>I am trying to:
  1) create a dynamic property
  2) bind that property to a label</p>
  
  <p>This works great for "sealed properties", but for dynamic properties there doesn't appear to be any event triggered.  Are dynamic properties <strong><em>implicityly not</em></strong> bindable?  </p>
  
  <pre><code>var myObj:MyType = new MyType(); // MyType is dynamic
  myObj["myDynamicPropertyName"] = "initialized";
  
  BindingUtils.bindProperty(myLabel, "data", myObj, repeatedLabel.name); // myLabel now displays "initialized"
  
  myObj["myDynamicPropertyName"] = "changed";  // myLabel still displays "initialized", it should say "changed" !!!
  </code></pre>
