Trying to call a root level function from within a loaded swf

Question

I'm not very familiar with AS3... I'm trying to have a loaded swf file call a function from the parent to unload itself when it comes to the end (on the timeline, not as a button). I'm assuming I need to be calling the function (that is used for the close button) from the loaded swf (perhaps I'm mistaken though?).
Here's the code from one of my buttons that loads an swf. I'm guessing I need to call the closeSWF function from the timeline of my loaded movie but having no luck figuring out how to do that.
Any help would be appreciated.
// 01 ------------------------------------------------------
function loadWeaving(ev:MouseEvent):void {
  // load SWF
  var movieClip:MovieClip = new holder_mc;
  //add it to the stage
  addChild(holderSWF);
  holderSWF.x=0;
  holderSWF.y=0;
  var requestEN:URLRequest = new URLRequest("WhatIsWeaving_Eng.swf"); // english
  holderSWF.load(requestEN);
  close_bt.addEventListener(MouseEvent.CLICK, closeSWF);
  function closeSWF(infoObject:Object):void {
  trace("close SWF");
  removeChild(holderSWF);
  // reset switch
  close_bt.visible = false;
  showAllButtons();
  infoObject.currentTarget.removeEventListener(infoObject.type, closeSWF);
  setChildIndex(close_bt,numChildren - 1);
  close_bt.visible = true;
  hideAllButtons();
  // - start timer last
  myTimer.addEventListener(TimerEvent.TIMER, closeSWF);

You're exactly right. If you attach an event listener to the Loader before you add it to the stage, you can then use event.currentTarget to refer to the loader. And this is definitely the better way to do it if you're planning to use the loaded swf from multiple places or could ever need to do this in the future.
So:
protected function initLoader():void {
     var loader:Loader = new Loader();
     loader.addEventListener('closeMe', closeLoader);
     loader.load(new URLRequest(...));
     addChild(loader);
protected function closeLoader(e:Event):void {
     var loader:Loader = e.currentTarget as Loader;
     if (loader) {
          loader.unloadAnstop(true);
          loader.removeEventListener('closeMe', closeLoader);
          removeChild(loader);
