How to get multitouch input using EasyTouch

I have 'Easy Touch' plugin and its great! I'm able to implement most of the thing but i'm stuck at the multi-touch input.

I have to two big buttons on the screen with 3D collider if I tap any one of them they do their work perfectly the only problem is, there will be a situation where I have to tap both buttons. But when I press on those two buttons simultaneously only the first tap on the object gets input and does what it should do.

So plz help me doing multi-touch Input using EasyTouch plugin not custom code.

Thanks in advance
