Remove one from right side of two column select list

I need a choice where user clicks a button to remove top item plus send a message to user desktop.

Found this link, however to make it useful for me I need to make a copy of its remove one ( from right ) column.

How is it possible that with a click of a button the same action that happens with “<” button, happens here.

Hope, I am clear enough to put my point across. Let me know how it goes.
