How does Backbone.Model.Fetch() work (does not update the model)?

Question

JavaScript

I started to study Backbone, here is a piece of code that should pull data from the server into the model.
window.book = new App.Models.Book({id: 1});
book.fetch({reset: true, success: fetchSuccess});
var fetchSuccess = function(book) {
alert(book.get('title'));
};
When fetch() is called, the /books/1 request is sent, the chrome console confirms that the request has occurred and displays the desired book in response:
{"attributes":{"id":1,"title":"Lorem Ipsum","author" :"Dolor Sit Amet","isread":0},"original":{"id":1,"title":"Lorem Ipsum","author":"Dolor Sit Amet","isread":0} ,"relations":[],"exists":true,"
author: 'author',
isRead: false } Can you tell me
how fetch works, and what's the problem with not populating the model?
