Help Panasonic Genius Prestige Inverter Microwave plastic behind Lever Came Off?

I have a Luxury-Full Size 2.2 Cu. Ft. Genius Prestige Countertop/Built-In Microwave Oven with Inverter Technology, Stainless and the lever wouldn't open the door. So I opened it up and saw that a small piece had broken off so I fixed it with crazy glue. Thereafter, I tried placing it back on but it will not stay. After pushing the lever to open the door about 10 times, it comes back off though it clicks into place every time I put it back on. Please help me. I have taken pictures of it on and off the microwave and close up pictures of the part if that will help. Thank you!
