How to register squeeze response on triggers of oculus touch?

I have been trying to make the triggers on the oculus touch controllers respond just to a squeeze.

Based on the manual about getting input from the touch controllers I know that joystick button 15 responds to the secondary index trigger on the touch controller. But, if you use this button you register every touch of that button. I would only like to register a squeeze. Based on the manual I thought you had to specify the joystick axis as the 10th axis. But, if you make a button in the input manager that responds to joystick button 15 that only reads input from the 10th joystick axis, it still registers a touch of the button. When you only read input from the 10th joystick axis and do not specify a positive button name, then nothing is registered.

Does anybody know how you can only register a squeeze?

I am using Unity 5.5.1.

Thanks!

 

I figured it out. I had to use Input.GetAxis instead of Input.GetButtonDown.
