Comparator in backbone requires the sort call when adding a new model?

I defined the Comparator in my Backbone.Collection.

When I add a model to the that collection should I call the sort method?

this.collection.add(this.newModel);
this.collection.sort(); // should I add this line?

According the documentation not, but my app seems to need it. any idea?

I added jsfiddle..but I have another problem...any idea how to fix it?

It shouldn't be needed to call sort(), the comparator() method is used in every Collection insert.

Check the working example in jsFiddle

Your problem should be somewhere else.

No, use the negative sign when you return an object from your comparator function. This is another way to sort elements.

  //Model
     comparator: function(activity){

                var date = new Date(activity.get('created_at'));
                return -date.getTime();

            }

//View
 events : {
        'click .refresh' : 'refresh',
        'click .reverse' : 'reverse'
    },

    refresh : function() {

     this.collection.fetch();
    console.log('refresh', this.collection);
     this.render();

    },

    reverse : function() {

        var $ref = $(".notifyRefresh");

        console.log("you clicked reverse");

        console.log(this.collection, "collection");

        this.collection.sort();
    }
