// Make sure all change events on autocomplete fields happen before submit:
$(document).on( 'submit', '#facet-search', function( e, changeDone ) {
	changeDone	= changeDone || false;
	if( !changeDone ) {
		e.preventDefault();
		$( '.ui-autocomplete' ).trigger( 'change' );
		$( e.currentTarget ).trigger( 'submit', true );
	} else {
		return true;
	}
} );
