tree with contexmenu - add listeners for event

[Stanimir Marinov]

I have tree with contextmenu. How can I write with struts2-jquery plugin:
.on('changed.jstree'.. with ajax request like this: http://wp.wikirex.com/2014/04/13/contextmenu-plugin/
and this is complete example - view HTML source:
http://www.jstree.com/demo_sitebrowser/

I need to have simple generated from struts2 plugin JavaScript: 

  $('#some_tree').on(...// listeners for event

<sjt:tree
        name="groupsTree"
        id="groups_tree_id"
        href="%{treeDataUrl}"
        jstreetheme="apple"
        onClickTopics="treeGroupsClicked"

        contextmenu="{
                        items: {
                                'create' : {
                                        'label': 'New',
                                        'action':  function (obj) { console.log(obj); this.create(obj); ajaxExec('%{editNode}', {'groupsId': obj[0].id,'editaction':1}); }
                                },
                                'rename' : {
                                        'label': 'Rename',
                                        'action':  function (obj) {  return { renameItem: this.rename(obj) };  }
                                },
                                'ccp' : {
                                        'label': 'CCP',
                                        'action':  function (obj) { ajaxExec('%{editNode}', {'groupsId': obj[0].id,'editaction':3}); }
                                },
                                'remove' : {
                                        'label': 'Delete',
                                        'action':  function (obj) { this.remove(obj); ajaxExec('%{editNode}', {'groupsId': obj[0].id,'editaction':0}); }
                                }
                        }
                }"
        />

Its better to have JavaScript with events and not to try with custom items in contextmenu ="{}"
https://github.com/vakata/jstree/issues/1030

elem.on('delete_node.jstree', function (event, data) {
    console.log(event);
    console.log(data);
}).on('create_node.jstree', function (event, data) {
    console.log(data.rslt.parent.id);
    ajaxExec(url, {'groupsId': data.rslt.parent.id, 'editAction': 2});
}).on('rename_node.jstree', function (event, data) {
    console.log(data.rslt.obj[0].id);
    console.log(data.rslt.name);
    ajaxExec(url, {'groupsId': data.rslt.obj[0].id, 'name': data.rslt.name, 'editAction': 1});
}).on('move_node.jstree', function (event, data) {
    console.log(event);
}).on('copy_node.jstree', function (event, data) {
    console.log(event);
});
