Mc.onPress not working w/ createEmptyMC

This code isn’t working for me. I have written the same thing a bazillion times, but for some reason this isn’t working for me right now…:


this.createEmptyMovieClip("container", -1);
for (ii=0; ii<xml_obj.firstChild.childNodes.length; ii++) {
                container.duplicateMovieClip("cp"+ii, ii);
	ext = this["cp"+ii];
	ext.onPress = function() {
		trace("onPress called");
	};
}

The MCs load into my scrollPane and everything fine, but they don’t respond to the onPress… Any idea why its not working?
