Title: Form field type checkbox does not work - Proposed Fix

I tried to put checkbox form fields into my custom component using xml forms. In my fieldset there is included:

<field
name="named_checkbox"
type="checkbox"
label="COM_COMPONENT_CHECKBOX_LABEL"
description="COM_COMPONENT_CHECKBOX_DESC"
class="inputbox"
value="1"
default="0"
/>

The checkbox saves fine when it is checked. However when I try to uncheck the checkbox, it does not update the database. After this change any checkbox form element should save value 0 when the checkbox is unchecked.
