         var MyCollection = new Backbone.Collection();

         //The on() method binds callback function to 'MyCollection' instance and invokes whenever an event triggers
         MyCollection.on("change:title", function(model) {

            //When event triggers, it retrieves the title from the collection
            document.write("JavaTpoint-- " + model.get('title'));
         });
         MyCollection.add({id: 2});  //adds id value as 2 in the collection

         //The 'myvalues' object gets the 'MyCollection' with id = 2
         var myvalues = MyCollection.get(2);

         //Sets the value for the title
         myvalues.set('title', 'A Solution of All Technology.');
