Since 1.1 or 1.1.0.2 there is a bug where the button doesnt activate a redstone device when its not directly on it.
Like when i putted the button on the block on front or next to it then nothing happend.But in previous version of mcpe it did even work when it was on the block on front or next to it and also in other platforms the button works properly.

It seems to have got fixed in the mcpe 1.2 beta but its worth to double check just to be sure.
