jquery - Getting this from javascript event listener in backbone.js -

so touch devices have couple of event listeners touchstart , touchmove. else has events bound jquery, reason didn't work touch events bound using javascript:

document.addeventlistener('touchstart', this.touchstart); document.addeventlistener('touchmove', this.touchmove); 

the problem when want trigger event jquery bound event, can use, example:

this.scrollcontainer(); 

however, context of this different within javascript bound event means cannot trigger event way.

my question is, possible trigger event javascript bound event? if so, how?

you need use _.bind() pass custom context callback

document.addeventlistener('touchstart', _.bind(this.touchstart, this)); document.addeventlistener('touchmove', _.bind(this.touchmove, this));
