Remove the inside door cover of an opel corsa?

I want to remove the inside cover of one back door from my opel corsa. I have removed the window wider, but I don't know how to remove the handle that opens the door from the inside. This handle is surrounded by a plastic that goes over the inside door cover, and prohibits it from removal. Any ideas on how to remove it?|||There should be a screw in there somewhere. When you pull the handle out to the "open" position it should reveal where the little screw is. Good luck.|||I cant remember how they come off but if there is no screw, it could push forward and come out or just click into place. Use a small screw driver to prise it out it wont take much as its only plastic. Im sure though the lever is one unit, so comes out complete and no outer shrouds.|||above where you open the handle theirs a circular plastic cap remove it and theirs a star head screw.|||the front half of the grab handle pulls off revelling two torx screws the actual handle can be left in place on the door card
