OnInputTouchBegin not firing anymore

i used OnInputTouchBegin to destroy my actor! Now its not working. I created another actor to check-with it working. In controller i enabled touch events.Where im wrong??

try a few things

1: change input key
2: double check the reference you are passing to deletion
3: enter debug mode and press play, while pressing your key, do you see the blueprint flow reaching the deletion point?
