</head>
<body>
<script type="text/javascript">
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("Hello... " + 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', 'Welcome to YiiBai');
</script>
</body>
