How to update the data on the site??

Question

ASP.NET

I do it like on the site , but for some reason the update place on the site just goes to another page. What's wrong:

@using (Ajax.BeginForm("ChangeTraining", new AjaxOptions { UpdateTargetId = "asdasda" }))

<div id="asdasda">

    </div>

[HttpPost]
    public ActionResult ChangeTraining()
    {
      return PartialView();
    }
