Mvc 3 nested object binding

I am very new to MVC 3, so this can be easy. I have a viewmodel with a nested object like this:

 public class EventViewModel
 {     
    public Event Event { get; set; }
 }

 public class Event
 {
    [Required]
    public int Id { get; set; }

    public string Title { get; set; }
 }

In my "create" view, I am doing something like this:

@model EventViewModel
@Html.EditorFor(model => model.Event.Title)

Here the code forms my event controller:

public class EventController : Controller
{

  [HttpPost]
  public ActionResult Create(EventViewModel @event)
  {
    ...
  }     
}

This editor is inside the form tag. When I get back to my controller, the title of the event will be null, not what I entered into the form. Do I need some kind of individual binder? Am I doing something unconventional when I use nested objects in my view model?

Oh right. When you request a page for the first time, that is, its default action, you need to create an instance of ViewModel and pass it to the view.

public ActionResult DefaultActionForEventView()
{
    var eventViewModel = new EventViewModel();
    eventViewModel.Event = new Event() // I can't remember if you need this line
    return View(eventViewModel) 
}

Let me know about the line above.
