1999 chevy tahoe sliding door handle

Hey all.

The driver side door handle came loose recently and I was wondering if I could fix it myself, or if I have to get it fixed by a shop because I know they are going to charge some ridiculous amount of money for a fix that I think I could do.  Any help would be appreciated - like a how-to on resetting the door handle, it just came loose; the spring is still there and all but I don't know how to put it back in the proper position.  Thanks in advance.

Pretty easy repair have a kid that does car audio installs help you get the inside door panel off the rest is a piece of cake.
