[AS2] Can AS add components?

Can AS add components that aren’t already linked from the library? I’d like to add a comboBox component using just AS. I tried this and it didn’t work:
[AS]createEmptyMovieClip(“dirChooser”,_root.getNextHighestDepth());
dirChooser.dirChoice = new ComboBox();
dirChooser.dirChoice.addItem(“greater than”);
dirChooser.dirChoice.addItem(“less than”);
dirChooser.dirChoice.addItem(“equal to”);[/AS]

When I viewed objects in the debugger, it only had this:

Movie Clip: Frame=0 Target=“_level0.dirChooser”

I’ve looked at the following pages about combo boxes and can’t find an answer to my question:
