Model Binding and Field name prefixes in Views

How does Model Binding work in combination with Field name prefixes in Views?

For example, here is my Edit Action in my Controller:

public ActionResult Edit(int id){
return View(GetItem(id));

And here is a Field in the Edit/Create View:

<%= Html.TextBox("myprefix.MyField") %>

This doesn't seem to work with field name prefixes; the input fields in the view aren't prepopulated with the values of the Model passed to the View. (If I remove the prefix, it works.)

The strange thing is that it works the other way around; when submitting my Create view to the Create controller, the binding works as expected.

How does this work? And why doesn't it work when passing a model to the Edit View?
