Action based input

Hi, I was checking out the action based input system. I tried to access the quest joystick or grip via code.
In my c# script I add the following:
public InputActionReference turnRef = null;
(via the unity editor I drag the XRI LeftHand/Turn action to).
In the start method of the script I subscribe myself to the event:
void Start()
{
turnRef.action.started += Action_started1;
}
And I log if I have an event:
private void Action_started1(InputAction.CallbackContext obj)
{
Debug.Log(“test”);
}
But I never got into the callback of the event. Any idea what I do wrong?

This should help you out:
