Force event endinput touch

In my tablet game, I did a click and drag manually but the moment i release my object on another object, the event end input touch dosen’t trigger. I bypassed it by steeling the controller and end it when the touch event is release. This work once but the event begininput touch won’t trigger again. Is there a way to tell my blueprint that event endinput touch happend or set beginenput touch able to be trigger again?
