adding an event to catch when a list item is added to a jQuery

adding an event to catch when a list item is added to a jQuery

I am using jQuery to add an event to a select (multiple) control. The idea
is to execute this event when an item is added or removed from the list. I
have tried the $("#myselect").change() function but this only throws the
event when you select another item in the list. Any help would be greatly
appreciated. Thanks in advance!
