It's working fine. You're probably testing on a desktop.
While the Touch on a touch-enabled device is recognized both as Touch and as Click, a mouse click, on a non-touch device, is only recognized as Click. So. If you test on a desktop computer with a mouse, the Touch event will never be activated.
Try going to http://constructgamelab.000webhostapp.com/test in a smartphone and you'll see it working.
