you are not tying your checkbox's model to the form's model object so it
saves into its own model..
as you can see here:
IModel checkedModel = new Model(customer.isOptedForNewsletter());
form.add(new CheckBox("optedForNewsletter", checkedModel));
you are giving it its own model...
so in your onsubmit you have to call checkbox.getmodelobject() to retrieve
the value, or give it a model that is properly tied to the form's model
object via a propertymodel or something else
