Remove stage listener for multiple movieclips

Question

I would like to completely remove personalized stage listeners, for each movieclip as soon as they are placed where they need to be, but the listeners remain every single time a new clip is dragged.
Thank you for any help!
function clickToDrag(targetClip:MovieClip):Function {
          return function(e:MouseEvent):void {
                    startingPosition[targetClip.name] = new Point(targetClip.x, targetClip.y);

                    setChildIndex(targetClip,numChildren - 1);
                    trace('clickToDrag function invoked\ntargetClip: ' + targetClip.name + '\startingPosition: ' + startingPosition[targetClip.name] + '\n\n');

i will try to show you a way that might help you to understand how the event-model in as3 is meant to work.
look at this code:
//with a MovieClip "DragClip" in the Library exoported for ActionScript
import flash.display.MovieClip;
import flash.events.MouseEvent;
for (var i:int = 0; i<10;i++){
    var mc:DragClip = new DragClip();
    addChild(mc);
    mc.mouseChildren = false;
    mc.addEventListener(MouseEvent.MOUSE_DOWN, dragStart);
    mc.addEventListener(MouseEvent.MOUSE_UP, dragStop);
    addChild(mc);
function dragStart(e:MouseEvent):void {
    e.currentTarget.startDrag();
    trace("dragging started");
function dragStop(e:MouseEvent):void {
    e.currentTarget.stopDrag();
    trace("dragging stopped");
    e.currentTarget.removeEventListener(MouseEvent.MOUSE_DOWN, dragStart);
    e.currentTarget.removeEventListener(MouseEvent.MOUSE_UP, dragStop);
//it places hundred Movieclips on the stage
//makes them draggable
//but after they are dragged once
//they stay in place
