Mobile joystick and UMG

Hi friends!
I try to build twin stick FPS. Problem is when I move my character with left stick, UMG button (“fire” fo example) can react for my tap, can show no reaction at all.
As I know there is no way to build sticks in UMG, so if anyone have idea of solid FPS controls for mobile, please let me know!

Sorry for bad English!
