Touch Input did work perfectly but smth happened and now it doesn't anymore

Hey guys !
I’m trying to make a small mobile game for ios and did follow Devin Curry’s tutorial (http://forum.unity3d.com/threads/tutorial-making-a-2d-platformer-with-touch-buttons-for-mobile.291780/) to implement the touch buttons.

I use unity remote and it worked perfectly the 5 first minutes, then i did build the project by accident and now the buttons doesn’t respond on unity remote.
It does work in the editor when i click on it tho, but testing my game on mobile was fun so i wonder if there is a way to get it back…

I’m not sure if you need my script since it did work before and i didn’t change anything in it.
Anyway if you need it just ask me i’ll post it as soon as i see your message !

Thanks for the upcoming help guys !

I find that sometimes my Unity Editor switches back to “PC/Windows” as the project default, and I have to go in to Build Settings and switch it back to iOS or Android.
