Interaction SDK for Unreal Engine

It's a simple question, in the IsdkSamplePawn, in the EventGrapth, when I add an Enhanced Input Action (for example IA_AButton_Down) ,  when I press the A button nothing happens. 
What I need is to listing the inputs from the hands or controllers so I can call actions for them ( for example I can build a Teleport sistem taken from the UE Vr Template ). 
Thanks.
