Ajax.BeginForm partial view replace whole page

Question

I had some problem in my MVC application, when I use button (submit) everything is okay but if I use onchange, partial view opened in the same window not replaced any div, I use all methods what I see here, but nothing help, here all code (any does not work correctly). Why its Happens?

Controller:

public class HomeController : Controller
{
    public ActionResult Index()
    {
        List<string> Year = new List<string>();
        Year.Add("1");
        Year.Add("2");
        Year.Add("3");
        Year.Add("4");
        ViewBag.Years = new SelectList(Year);
        return View();
    }
 public PartialViewResult testt()
    {
        return PartialView();
    }
    [HttpPost]
public PartialViewResult testTwo()
        {
            return PartialView();
        }
}

View (I am include on my page all scripts unobtrusive ajax, microsoft ajax, jquery and many others):

<script src="~/Scripts/respond.min.js"></script>

@using (Ajax.BeginForm("testTwo", new AjaxOptions { HttpMethod = "POST", UpdateTargetId = "testDiv", InsertionMode = InsertionMode.Replace }))

    <div>
        @Html.DropDownList("Years", (SelectList)ViewBag.Years, new { onchange = "this.form.onsubmit()" })
    </div>
</div>
}

You have to include

@section scripts {
    @Scripts.Render("~/bundles/jqueryval")
}

this in your page, else it won't work. Try like this, and not with the script tag.
