Flash button controled by flex issue

Question

In flex I can only reference the flash button by its ID property.
Most of the time I can't know its ID. I need cover it to a super class like MovieClip Instead of that.
I created the button in flash by the following steps:
design button -> cover symbol to flex component -> use it in flex
How can I fix this ?
<mx:Script>
  <![CDATA[
   private function clickHandler(event:MouseEvent):void
      /* not work */
    MovieClip(event.target).gotoAndPlay(MovieClip(event.target).currentLabel);
     /* only this way can run */
    query.gotoAndPlay(query.currentLabel);
  ]]>
</mx:Script>
<local:intergratedQueryButton id="query" click="clickHandler(event)" x="305" y="500"/>
