Oculus camera rotation

Hi everyone

I am trying to get Oculus Rift DK2 working with my WebGL Javascript code.
I am attaching WebVRFreeCamera to my canvas in the scene.
I can see that some head tracking happening but unfortunately in the wrong directions.
For example if I rotate my head about X axis canvas rotates in Z axis and vice versa.

Did anyone has experimented this before? Any solution?

Thanks..
