None of button clicks not taking in Unity/device

I am trying to develop a simple application using Unity.

I can able play YouTube videos, but none of button click not working in unity and glass.

I have tried with sample file also the same. I can able to control ray cast and able select a object but events not triggering. Please help…

Thanks in advance

Can you explain more please. What are you playing the video on? A unity component or a plugin or your own script?

What interfaces are you implementing in your component to detect the interactions?
