pinch not working with firefox

[ghost]

I add this code to QuoJS-master/spec/test/gestures.html. Chrome is ok but firefox is fail. How can I fix this? thanks.

$$("section.green").pinch(function() { $$(this).append(' | pinch'); });

I'm sorry but multitouch events depends of browser capacities... and for now Firefox (such as WP8) doesn't have a good support.
