ListBox tutorial : Version question

I was checking out the kirupa tutorial on List Box. Following along with flash 8 I used a “List” item not a ListBox. I was able to add items to the listbox as per tutorial but the setChangeHandler line did not work.

I can’t see how the tutorial is newer than flash 8, so I fail to see what i’m missing. Can a flash 8 list component have an on change event?
