Camera control on phone not working for babylonjs vr

I can't manage to get the camera control to work on a phone using babylon defaultVRExperience

I can't understand what's missing. i've tried everything i can think of and i can't find any examples that work outside of the babylonjs playground.

Example of it working perfectly in babylon playground with just a few lines of code: https://www.babylonjs-playground.com/#VIGXA3#38

Example of same code not working outside of babylon: http://jsfiddle.net/dr3k5oqb/

Here's an example with some stuff i found in an article about making vr stuff for phones with babylon.. not working either: https://jsfiddle.net/2cdLw0tk/2/

Literally any help would be greatly appreciated...
