DS4 Controller FUN!

Okay so I recently discovered the DS4 controller and wanted to have a little fun playing League with a PS4 controller. The left and right mouse clicks work for me. However it seems that the skills don't work. QWER and any other keys don't seem to work. After pressing "Enter" then typing it seems to register fine, but not when i'm in battle or anything.

Again this is just for fun but i'm hoping that someone out there knows how to fix this problem for me. The program of course works for steam and such, just not for league xD
