And finally i solve that problem. If you are using a checkbox; uncheck Allow Nulls option of your field in your DB. That's it!

You could use the following:

@Html.CheckBox("SKUs.Jewish", Model.SKUs.Jewish.GetValueOrDefault());

If the value is not set it uses the nullable types default value which is false.

With a nullable type you check if it has a value with thing.HasValue, and get at the actual value using thing.Value.
