Ah I see. Looks like the handle has come adrift from the door panel. It's clipped with a twist ring thing. I'm sure that your going to need the whole door card assembly, unless you can fix what you have there. The twist clip isn't available I don't think. The best thing is to get the door card off, so you can see how what's damaged. Then you can decide if it's fixable, or you need a replacement door card.
There's the twist clip viewed from the back. I might have one of those, although I've know idea where.
