Why watch function calling multiple times???

[abdheshkumar]

Hi, I just use your angular directive code for scroll bottom in chat box but i realized watch function calling number of times. According to angular documentation it should be call only two times. so could you tell me why it is calling multiple times?

scope.$watch should only be called once per scroll-glue tag used in your markup. Can you elaborate with an example?

@Luegg Thanks for quick reply. No, scope.$watch calling two times when i used it in separate directive(in parent directive). When i used in child directive it's calling multiple times and even calling continuously but parent directive already implemented scope.$watch for some object changes. so it may be happening because of parent directive scope.$watch implementation ?
