OnCommit in textbox in VR stops everything(motioncontroller, buttons) Nothing works!

Hello,
I made a textbox widget and added it to the viewport when eventbegin play. Now to enter text into it, I enabled mouse cursor and so I select it and enter the string into it(during gameplay).

But when I hit enter, everything stops working ! Motion controllers would just hung up and no keyboard buttons actions would works. I am stuck onto this for a long time !

This is the event graph for the widget !

This is when i am adding the widget to eventbegin play in motioncontroller pawn

This is drawname - custom event for widget creation !
