Incorrect label setup when creating custom layout

[Jono M]

Steps to reproduce

- "Edit layout" on any page
- Open "Create custom layout", change some stuff and click "Create new layout"
- Without refreshing the page, inspect the newly created radio button and its associated label

The radio button ID and label 'for' attribute don't match, and the label contains the text "100" instead of an accurate representation of the layout. If you refresh the page the label and radio button will be set up properly, so this only happens when the option is added with JavaScript.
