ActionScript 2.0 :: Assigning Events To Dynamic MovieClips?

I load an XML file and through it create several Movie Clips. I want each movie clip to have a rollover and mouse click event, yet assigning the events does not seem to work at all. Here is how I create everything:

ActionScript Code:
var parsed_obj = new Object(); //This will hold the parsed xml data (once the XML loads and gets parsed).
XMLParser.load("xml/test3.xml", onFinish, parsed_obj);
function onFinish(success_boolean, anXML, xml) {
//This function gets called when the XML gets parsed.
if (success_boolean) {
LoadImages(anXML);
CreateAlphabeticalArray();
[Code] .....

When the XML successfully loads, we put it in a global variable and then create images based off the xml data. It might be a little verbose, but it gets the job done for now. I tried several methods creating objects to hold the events and attaching them, just using .onRollOver = function() { trace("whatever") };, etc. The code is on Frame 1 of the time line and not attached to anything. I experimented attaching it to a movie clip and doing onClipEvents, but that breaks the rest of my code because there are various sorting functions and button presses that don't get called.
