Using MVC to create a database entry of type Player:

```
[HttpPost]
public ActionResult Create(FormCollection fc, Player player)
{
    players.Players.InsertOnSubmit(player);
    players.SubmitChanges();

    Errors errors;
    if (!IsValid(player, out errors))
    {
        ViewBag.Errors = errors;
        return RedirectToAction("Edit", player);
    }

    return Redirect("/Home/Players");
}

[HttpPost]
public ActionResult Edit(FormCollection fc, Player player)
{
    players.SubmitChanges();

    return Redirect("/Home/Players");
}

```

My problem is that `players.SubmitChanges()` in the Edit method doesn't change anything in the database. Using `InsertObSubmit` in Create works. Shall I do it in another way?
