Changes .bind to .on

[wmill]

.on will work on newly created elements, .bind will not.

This will fix some issues I had using jquery-ui-touch-punch with AngularJS.

Plus, "As of jQuery 1.7, the .on() method is the preferred method for attaching event handlers to a document."

May be modernized even more:

    self.element.on({
        'touchstart': $.proxy(self, '_touchStart'),
        'touchmove': $.proxy(self, '_touchMove'),
        'touchend': $.proxy(self, '_touchEnd')
    });

And for removing the event handlers

self.element.off({
'touchstart': $.proxy(self, '_touchStart'),
'touchmove': $.proxy(self, '_touchMove'),
'touchend': $.proxy(self, '_touchEnd')
});
