Ajax.BeginForm redirects action page(MVC 4) - asp.net-mvc

Question

I use 'Ajax.BeginForm' in my application,but for some reason my form is redirecting to {controller}/{action} with right json data instead of start {OnComplete = "Add_OnComplete"}:
View:
<script src="#Url.Content("~/Scripts/jquery.unobtrusive-ajax.js")" type="text/javascript"></script>
<script src="#Url.Content("~/Scripts/jquery.validate.js")" type="text/javascript"></script>
<script src="#Url.Content("~/Scripts/jquery.validate.unobtrusive.js")" type="text/javascript"></script>
#using (Ajax.BeginForm("Create", new AjaxOptions { OnComplete = "Add_OnComplete"}))
{
<fieldset>
<legend>Add</legend>
<div class="editor-label">
#Html.LabelFor(model => model.FullName)
</div>
<div class="editor-field">
#Html.TextBoxFor(model => model.FullName)
#Html.ValidationMessageFor(model => model.FullName)
</div>
<div class="editor-label">
#Html.LabelFor(model => model.Email)
</div>
<div class="editor-field">
#Html.TextBoxFor(model => model.Email)
#Html.ValidationMessageFor(model => model.Email)
</div>
<div class="editor-label">
#Html.LabelFor(model => model.PhoneNumber)
</div>
<div class="editor-field">
#Html.TextBoxFor(model => model.PhoneNumber)
#Html.ValidationMessageFor(model => model.PhoneNumber)
</div>
<div class="editor-label">
#Html.LabelFor(model => model.Status)
</div>
<div class="editor-field">
#Html.TextBoxFor(model => model.Status)
#Html.ValidationMessageFor(model => model.Status)
</div>
<p>
<input type="submit" value="Create" />
</p>
</fieldset>
}
<script type="text/javascript">
function Add_OnComplete(context) {
var JsonAdd = context.get_response().get_object();
if (JsonAdd.Success) {
//TODO
}
}
</script>
Controller:
public PartialViewResult Create()
{
return PartialView();
}
[HttpPost]
public JsonResult Create(Subscribe model)
{
if (ModelState.IsValid)
{
_entity.CreateSubscribe(model, SubscribeStatus.Customer.GetHashCode());
var message = new Message(MailSubject, MailBody, model.Email);
message.Send();
}
return Json(new
{
Success = true,
Message = "The person has been added!"
});
}
What I do wrong ? And what am I missing?
Thanks.

Remove that get_response().get_object() stuff.
Use just context.Success
