привязка jstree с отправкой данных json из контроллера mvc

My controller

[ScriptMethod(ResponseFormat = ResponseFormat.Json)]
        public JsonResult GetAllNodes()
        {

            List<Employee> pEmployee = new List<Employee>();
            Employee tEmployee = new Employee();
            tEmployee.EMP_ID = 1;
            tEmployee.EMP_NAME = "steve";
            tEmployee.PARENT_EMP_ID = 0;
            pEmployee.Add(tEmployee);

            tEmployee = new Employee();
            tEmployee.EMP_ID = 2;
            tEmployee.EMP_NAME = "Joe";
            tEmployee.PARENT_EMP_ID = 1;
            pEmployee.Add(tEmployee);


            tEmployee = new Employee();
            tEmployee.EMP_ID = 3;
            tEmployee.EMP_NAME = "Eric";
            tEmployee.PARENT_EMP_ID = 1;
            pEmployee.Add(tEmployee);

            tEmployee = new Employee();
            tEmployee.EMP_ID = 4;
            tEmployee.EMP_NAME = "Henry";
            tEmployee.PARENT_EMP_ID = 0;
            pEmployee.Add(tEmployee);

            tEmployee = new Employee();
            tEmployee.EMP_ID = 5;
            tEmployee.EMP_NAME = "Katie";
            tEmployee.PARENT_EMP_ID = 4;
            pEmployee.Add(tEmployee);

            tEmployee = new Employee();
            tEmployee.EMP_ID = 6;
            tEmployee.EMP_NAME = "george";
            tEmployee.PARENT_EMP_ID = 4;
            pEmployee.Add(tEmployee);

            tEmployee = new Employee();
            tEmployee.EMP_ID = 7;
            tEmployee.EMP_NAME = "Renai";
            tEmployee.PARENT_EMP_ID = 0;
            pEmployee.Add(tEmployee);

            tEmployee = new Employee();
            tEmployee.EMP_ID = 8;
            tEmployee.EMP_NAME = "Marc";
            tEmployee.PARENT_EMP_ID = 7;
            pEmployee.Add(tEmployee);

            tEmployee = new Employee();
            tEmployee.EMP_ID = 9;
            tEmployee.EMP_NAME = "John";
            tEmployee.PARENT_EMP_ID = 7;
            pEmployee.Add(tEmployee);

            tEmployee = new Employee();
            tEmployee.EMP_ID = 10;
            tEmployee.EMP_NAME = "Andrew";
            tEmployee.PARENT_EMP_ID = 0;
            pEmployee.Add(tEmployee);

            return Json(pEmployee, JsonRequestBehavior.AllowGet);
         //   return pEmployee;
        }

View

<script type="text/javascript">


    $(document).ready(function () {
        $.getJSON("Employee/GetAllNodes", function (result) {
            alert(result);
            alert(JSON.stringify(result));
            $("#treeViewDiv").jstree({
                "plugins": ["themes", JSON.stringify(result)]
            });
        });
    });
</script>

Now the issue is that when result comes from controller ,it doesnt bind to jstree.How to bind the data to jstree.
