How can I call functions from a SWF loaded in to another SWF?

Question

Hi there,
Please excuse my ignorance, I am very new to actionscript and flash.
I have 2 SWF's - a.swf and b.swf.
I load b.swf into a.swf with the following code:
var swfLoader:MovieClipLoader = new MovieClipLoader();
swfLoader.loadClip("b.swf", container_mc);
Now in b.swf, I have a function as follows:
public function sendData(){
  trace("I ran the function!");
So I have done a lot of reading, from what I can tell I should be able to run the sendData() function from the code in a.swf, by typing:
container_mc.sendData();
but its not working. What am I doing wrong?
Thanks in advance,
Adam

Thanks heaps mate, after a bit of trial and error it works! Here is the code that I added:
var loadingListener:Object = new Object();
swfLoader.addListener(loadingListener);
loadingListener.onLoadStart = function(container:MovieClip):Void  {
    trace("The MovieClip "+container+" started loading");
loadingListener.onLoadInit = function(container:MovieClip):Void
    trace("The MovieClip " + container + " has been initialized");
  container_mc.test();
Marked your answer as correct :-)
Thanks again, I really appreciate your help.
Cheers
