UE5 VR switch between free and snap turn not working

Hi, I’m trying setting up a widget with some VR player settings. In these player settings the player can choose between Snap Turn and Free Turn. The problem is I can’t seem te be getting the buttons to switch between these two rotation methods. Can someone point me in the right direction what to do? If I change the variable ‘Turn Mode’ at the BP_VRCharacter it works so I think I’m doing something wrong in the EventGraph of the widget itself. But can’t seem to figure out how to let the buttons change this variable…

Picture 01 is the BP_VRCharacter with the switch Enum.
Picture 02 is the widget with the buttons.
Picture 03 is the EventGraph of the widget.
