Front internal door handles - how to re-attach them?

Hello!

Found this great site after a quick stroll through the interwebs while trying to figure out how to re-attach the internal door handles (in the front side). By handles, I mean the ones you grip to close the door, not the metalic "latch" type ones that are used to open the doors.

The problem occourred when the previous owner decided to do some tinkering (he didn't tell me the reason) and didn't know how to re-attach them. They are abit wobbly and seem to be missing some parts (seems like a few screws).

Would be great if anyone has a guide or a diagram regarding the subject, or just the general know-how

Thanks in advance!

P.S

The Yeti in question is the 2012 model with the Ambition trim level.
