X button works only when the controller is disassembled

I have a PS4 controller that works fine except for the X button, I opened it then cleaned it, and before reassembling it I put the rubber part that goes above the circuit board and pressed the X button. It worked fine, but when I closed the front shell and tried it it wouldn't work, I then opened it and tried again with only the rubber part, it worked but when I closed it again it didn't work.[br]

what could be the problem?
