How to trigger a MouseEvent from TLF, my test doesn't work

Question

  Hi,
      I run into a problem while using the Listener of TLF,
      Inside  the  TextFlow,  I have several Paragraphs.
      What I wish to accomplish is to trigger a mouse Event, like ROLL_OVER, ROLL_OUT event , when  my mouse is over a on one of the Paragraphs.
      I used to experiment a while , but never seem to work, just the examples below
      _textFlow.addEventListener(FlowElementMouseEvent.ROLL_OUT,onMouseHandler);
      _textFlow.addEventListener(FlowElementMouseEvent.ROLL_OVER,onMouseHandler);
       ///   which doesn't work.         i need the event response ,so i can manipulate the paragraph
private function onMouseHandler(e:FlowElementMouseEvent):void
     trace("onMouseHandler" +  e.type  );
     var para:ParagraphElement = e.flowElement.getParagraph();
     trace(para.textLength);
Thanks  in   advance!!!
