Ajax.BeginForm is redirecting after putting all scripts and configured in web.config

Hello,

I am working on html.beginform and ajax.beginform. lot of article and blog saying that ajax.beginform() will not redirect another view(page).

But for me it is redirecting. i have referred all scripts and configured in web.config too. all scripts are existing under scripts folder in solution file.

Note : i have tested using fiddler to check loading script or not. it is loading.

layout.cshtml

<script src="@Url.Content("~/Scripts/jquery.unobtrusive-ajax.min.js")" type="text/javascript"></script>
<script src="@Url.Content("~/Scripts/jquery-1.4.4.js")" type="text/javascript"></script>

web.config

<appSettings>
<add key="webpages:Version" value="3.0.0.0" />
<add key="webpages:Enabled" value="false" />
<add key="ClientValidationEnabled" value="true" />
<add key="UnobtrusiveJavaScriptEnabled" value="true" />
</appSettings>

my controller

public class HomeController : Controller
{

[HttpGet]
public ActionResult TestAjaxView()
{
ViewBag.Message = "This is a AJAX form";
return View();
}
[HttpPost]
[ActionName("TestAjaxView")]
public ActionResult TestAjaxRedirect()
{
return RedirectToAction("About", "Home", null);
}
public ActionResult About()
{
ViewBag.Message = "This is a about form";
return View();
}
}

my view : TestAjaxView.cshtml

@{
ViewBag.Title = "TestAjaxView";
}

<h2>TestAjaxView</h2>


@using (Ajax.BeginForm("TestAjaxView", "Home", new AjaxOptions {UpdateTargetId = "result" }))
{
<div id="result">
@Html.Label("This is Ajax Form")
<input type="submit" value="Redirect" class="btn btn-default" />
</div>
}

finally it is redirecting about.cshtml. how? what i did mistake?

help needed.
