Passenger side outside front door handle won't push in and open the door

My son was opening the door while it was locked from the inside he did this
repeatedly and when I hit the unlock button he opened the door at the same
time and something happened.  Now u can open the door from the inside but
not outside.  The outside handle is stuck in the open position and won't go
Bach in even when you push it in.  I popped the panel off and looks like some
silverfish piece is messed up if I push up on it the handle will close but the
piece won't stay as soon as I let go the handle went back out what can I do to
fix this
