Input binding Not Worked

Hi everyone
I simply created a blank project and after that in project setting>input I added a new action and named it TestJump. after that I assigned space bar to it.
I created my game mode and my character and assigned game to project setting and character to game mode.
but when I get InputAction TestJump Event in my character event graph blue print nothings happened.
I added break point to this event. but nothing happened.
let me tel you everything is fine in side scroller sample and all key binding events are raised there.
tnx lot

Ok
Really Excuse me I found the problem. I used Escape instead of Spacebar
