jsTree drag and drop with ajax

[Ignace Mella]

Hello, the problem with my code is that the node changes in the database but it doesn''t change from place. So the original idea of dnd doesn't work. 
When I replace an item, the ajax command runs, but it doesn't replace on the page.
What is the problem and what can I do?

AS.Http.post({
    action: "getTools"
}, function (res) {
    $('#tool-tree').jstree({
        'plugins': ["wholerow", "dnd"],
        'core' : {
            'data' : res,
            check_callback: function (op, node, parent, position, more) {
                if (op === "move_node" && more && more.core) {
                    var result = false;

                    $('#tool-tree').parent().addClass("dimmed");

                    AS.Http.post({
                        action: "updateTool",
                        toolId: node.id,
                        parentId: parent.id != "#" ? parent.id : null
                    }, function () {
                        result = true;
                        $('#tool-tree').parent().removeClass("dimmed");
                    });

                    return result;
                }
            },
            'themes': {
                'name': 'proton',
                'icons' : false,
                'responsive': true
            }
        },
        dnd: {
            inside_pos: "last"
        }
    });
});
