using OVR how can i detect which controller is an object grabbed by?

the controllers are associated with ltouch and rtouch to differentiate them, you can make the raycast only on one hand, or get which source sent the raycast. 

Isnt there an easier way, Ive also tried to debug log GrabbedBy and it says that my hands are flipped.
Also can I do it without raycasting.Basically I want do have a flashlight and i want to trigger it with the trigger button on the correct hand that is holding it.
