sortable cancel but remove sort item.

    $('.posts_page_rd-postorder_reorder-posts tbody').sortable({
        handle: '.reorder-handle',
        helper: 'clone',
        placeholder: 'ui-placeholder',
        revert: true,
        sort: function(event, ui) {
            if ($(this).hasClass('cancel')) {
                $(this).sortable('cancel');
            }
        },
        start: function(event, ui) {
            // fixed height for table row.
        },
        update: function(event, ui) {
            // on stopped sorting and position has changed.
        }
    });

This is my code. I add keypress listening on press escape key to add cancel class to the sortable. And in start: method if there is cancel class then cancel sorting.

Everything seems to working fine but when it cancelled the item were removed.
