Hi Stephane,
Try normal functions instead of arrow functions .on("start", function(d, i) {this.dragstarted(d,i)}) This will give you a workable this. or .on("start",this.dragstarted.bind(this)) And this will make sure the function is bound to the class, I think this your best option Regards Sander -- You received this message because you are subscribed to the Google Groups "Angular and AngularJS discussion" group.
