PreventDefault MouseDown on a mobile IconItemRenderer

Question

Hi,
I trying to cancel the mouseDown on custom itemrenderer that extends IconItemRenderer when it's on a certain state.
I add a state that named 'control'
              _controlState = new State()
                              _controlState.name = 'control'
                              _controlOverride = new Array()
                              var requestAddChild:AddChild = new AddChild(this,_requestIndicator)
                              var controlAddChild:AddChild = new AddChild(this,_controlLabel)
               var downEventHandler:SetEventHandler = new SetEventHandler(this,MouseEvent.MOUSE_DOWN)
               downEventHandler.target = this
               downEventHandler.handlerFunction = controlDownHandler
               this.states.push(_controlState);
and the controlDownHandler function follow
               protected function controlDownHandler (e:MouseEvent):void {
                                        e.preventDefault()
                         e.stopPropagation()
                                        //dispatchEvent(new DataRequestEvents(DataRequestEvents.DATA_REQUEST,true))
But the default MOUSE_DOWN event are not stoped. I've also tryed to simply add an EventListener.
I've alos tried to simply add an event listener inside overriden method createChildren:
          this.addEventListener(MouseEvent.MOUSE_DOWN,controlDownHandler
          protected function controlDownHandler (e:MouseEvent):void {
                         if (!dragging){
                              e.preventDefault()
                              e.stopPropagation()
                              //dispatchEvent(new DataRequestEvents(DataRequestEvents.DATA_REQUEST,true))
But, in this case, i can't drag the list up or down
Is there a way to reach this goal ?
Thank for helping .

Hi  Flex harUI!
I've a list that display the 12 more recent news.
My final goal is to add an itemRenderer at the end of the list that can call a service that get older news.
1- The classic item render with default MOUSE_DOWN event. (call another view)
2 -The added itemRenderer that preventDefault() and call the service
Everything work fine exept that i can avoid the MOUSE_DOWN event on this particular renderer.
