Movie clip RemoveEventListener isn't working - AS3

Question

Friends,
what seems to be a pretty straightforward code doesn't seem to work. I have a movieclip on the stage( this is on the second frame while the first one is the login screen). On this movie clip i load a textarea.
When the screen goes from 1 to 2, i setup a zoom listener on the movie clip. Once the user initiates a zoom on the movie clip, i add two move event listeners (mouse down and up) to drag the movie clip. After all is done, i restore the movie clip to it's original position. In this restore code, i remove the mouse down and up events. But i don't think the remove event listener is working as i could still drag the clip(mouse down and up events are still active).
What could be the issue ? Am i missing something here ?
Thanks

Answer 1

This is onZoom();
public function onZoom(event:TransformGestureEvent):void
            // When the stage throws the gesture zoom event, enlarge the stage.
            event.stopImmediatePropagation();
            scStage.scaleX *= event.scaleX;
            scStage.scaleY = scStage.scaleX;
            if ( ! scStage.hasEventListener(MouseEvent.MOUSE_DOWN) ){
                scStage.addEventListener(MouseEvent.MOUSE_DOWN, onDown);
            if ( ! scStage.hasEventListener(MouseEvent.MOUSE_UP) ){
                scStage.addEventListener(MouseEvent.MOUSE_UP, onUp);
and this is restore code - both are in the same frame;
public function onRestore(event:MouseEvent):void{
            scStage.width = mwidth;
            scStage.height = mheight;
            scStage.x = mx;
            scStage.y = my;
            scStage.removeEventListener(MouseEvent.MOUSE_DOWN, onRemove);
            scStage.removeEventListener(MouseEvent.MOUSE_UP, onRemove);
scStage is the movie clip.
however, i solved this problem in a different way as the eventlistener removal didn't work. if the component has been restored to the original position, i take appropriate action. thanks for your time.
