Clonable fields within clonable fields are not working with certain fields

	group.toggle.updateTitle = function ( index, element ) {
		var $group = $( element ),
			$title = $group.find( '> .rwmb-group-title, > .rwmb-input > .rwmb-group-title' ),
			options = $title.data( 'options' ),
			content;
		
		if( 'undefined' == typeof options )
			return;
		
		if ( 'text' === options.type ) {
			content = options.content.replace( '{#}', index );
		}
		if ( 'field' === options.type ) {
			var fieldId = $title.data( 'options' ).field,
				$field = $group.find( ':input[name*="[' + fieldId + ']"]' );

			content = $field.val();
			if ( $field.is( 'select' ) ) {
				content = $field.find( 'option:selected' ).text();
			}

			// Update title when field's value is changed.
			if ( ! $field.data( 'update-group-title' ) ) {
				$field.on( 'keyup change', _.debounce( function () {
					group.toggle.updateTitle( 0, element );
				}, 250 ) ).data( 'update-group-title', true );
			}
		}
		$title.text( content );
	};

Initial testing of 1.2.4 seems to have solved this issue, however not without adding

if( 'undefined' == typeof options )
	return;

As I got 'type' undefined on some fields. Adding above in seems to solve that.
