I am trying to do something along the lines of the following where I have a Controller with an method similar to:

public ActionResult Insert(Author author) {
  //do something...
}

Where the Author type looks like:

public class Author {
  public string FirstName { get; set; }
  public string LastName { get; set; }
  public Book[] Books { get; set; }

  public Author() {
    Books = new Book[0];
  }
}

public class Book {
  public string Title { get; set; }
  public int NumberOfPages { get; set; }
}

From a page I want to submit data using JQuery and Ajax something like

function addAuthor() {
  var auth = {
    'FirstName': 'Roald',
    'LastName': 'Dahl',
    'Books': [
      {
        'Title': 'Charlie and the Chocolate Factory',
        'NumberOfPages': 264
      },
      {
        'Title': 'The Twits',
        'NumberOfPages': 316
      }
    ]
  };

  $.ajax({
    type: "GET",
    url: "/Insert",
    data: auth
  });

}

MVC binds the Author object (FirstName and LastName are set) but doesn't bind the Books property. Why is that and how can I submit an object containing an Array (or a Collection) as a property through AJAX?
