Oculus Rift controller input doesn't work

Hi!

I’m trying to set up a touch controller for tracking a camera. The controllers are working properly in SteamVR. However inside Unreal I only get the rotation information. No input from the buttons whatsoever. I have mapped the buttons in Project Settings/Input. I checked same actions with keyboard buttons mapped to the instead and tha was working.

Any ideas why the controllers’ input is not coming to Unreal?
