iOS touch and standard unity UI button

Unity Engine

I was in believe that Unity standard UI button on Canvas works directly with iOS devices. I have setup in Photon environment (Unity 5) and when I tap the button, only some parts of code are executed.
If I tap the button multiple times quickly all the parts of code is executed and button works just like in editor.

Suggestions how to get button working without having to tap it multiple times?

I have solved this. Root cause seems to be incorrect photon script location. I had script that was part of instantiated character and when I used this script to send RPCs, the RPCs were send and received but there was weird code behaviour because of photonviews. When I moved this script to be part of scene, everything works as intended.
