GE Profile Spacemaker ?

I have a GE Profile Spacemaker over the range convection microwave model JVM 1490CD003 and the handle broke at the bottom part of where it is attached to the door. I don't see any screws and it looks like maybe it is glued in? I was able to push it back in place temporarily, tight fit, and can open door by placing hand on top section of handle, but afraid it will pull out completely. Can you tell me how to fix this?
