ViewBag change using ajax in ASP.NET MVC3

ViewBag, ViewData, TempData are called just once at the first time when I call the view?

And never change if I don't refresh the page?

Because I want to change using Ajax (every 10 sec, I call Ajax)

Plz See below code,

==================== in Controller... =======================

 public ActionResult OriginView()
 {

      ViewBag.IntData = 1;

      return View();

 }


 public JsonResult ChangeViewBag(int CurrentInterval)
 {

      ViewBag.IntData = CurrentInterval;

      return Json(new{IntData=CurrentInterval},JsonRequestBehavior.AllowGet);

 }

================= in OriginView.cshtml... =======================

 var CurrentInterval = 2

 $.getJSON('@Url.Action("ChangeViewBag","Controller")', {CurrentInterval:CurrentInterval},function(response){

    @*CurrentInterval++ every ten sec, I want to use CHANGED ViewBag here!*@

    alert(@ViewBag.IntData) @*but **Result is still 1**, unchanged!*@

    alert(response.IntData) @*ofcourse I can use it in this way. *@

    @* but I should use below ASP.NET CODE

    @{
       string TimeData = DateTime.Now.AddSeconds(**ViewBag.IntData**).ToString();
    }

    ***The position is impossible to javascript variable.*** right?*@
 });

.Net genius please!!! If it's impossible, Any Idea?

ViewData / ViewBag(this is a wrapper around ViewData) are used to pass data between a controller to a view and they are re-created in every request whether it's AJAX or normal. They don't help you to maintain state :(
