Description

When changes directory type, the search form markup is replaced via AJAX. The original code bound events directly to elements that existed at initialization.

Before:

• Events were bound directly: $(field.input_elm).on('keyup', ...)
• When the DOM was replaced, the old elements (and their handlers) were removed
• New elements had no handlers, so the AJAX didn't trigger

After (a directory type change):

• The form markup is replaced
• New location input fields are added
• The delegated handler on body catches keyup events on the new inputs
• The OpenStreetMap AJAX request triggers correctly
