jquery - jstree : how to undelete / restore a node -

i using jstree in application contextmenu plugin.

when deleting node, have ajax request performs operation on database.

i'd delete node view if ajax returns operation = true parameter.

how can undelete jstree node has been deleted following code :

function (data) {     var inst = $.jstree.reference(data.reference),         obj = inst.get_node(data.reference);     if(inst.is_selected(obj)) {         inst.delete_node(inst.get_selected());     }     else {         inst.delete_node(obj);     } } 

i delete node tree when call successful. doesn't make sense delete node first, make call , if fails try re-add node. here example delete node if ajax call success:

var node = $('#tree').jstree('get_selected');  $.ajax({     url: link,     type: 'get',     data: { id: node.attr('id') },     async: false,     success: function (data, text) {         $('#tree').jstree('delete_node', node);     },     error: function (request, status, error) {     } }); 

ps. current selected node
