Backbone.js model.set not working

Question

I am trying to use the backbone.js model.set property. The second warning function should fire after executing the todo1.set command. However, it is not. Here is the jsfiddle link: http://jsfiddle.net/SGEkn/

var Todo = Backbone.Model.extend({ defaults: { title: "Harsh", completed: false }, initialize: function() { console.log('This model has been initialized.') } }); var todo2 = new Todo({ title: 'Set through instantiation.', completed: true }); console.log('Todo title: ' + todo2.get('title')); console.log('Todo completed ' + todo2.get('completed')); alert("ok"); todo2.set("title", 'Title set'); alert("ok"); console.log(todo2.get('title')); todo.set("completed", false); console.log('completed: ' + todo2.get('completed')); 

Answer 1

You must pass the object, not the arguments individually.

 todo2.set({"title":'Title set'});
