C＃.NET MVC Ajax表单提交

Feel like I'm missing something simple here - When I submit this form it takes me to a white page with my encoded JSON model, rather than staying on the page I was on.

Form in a partial view, loaded on every page:

@using (Ajax.BeginForm("Inquiry", "Home", new AjaxOptions { HttpMethod = "POST", OnSuccess = "success" }))

And my actions:

    public ActionResult Inquiry()
    {
        return PartialView("_Inquiry",new Inquiry());
    }

    [HttpPost]
    public JsonResult Inquiry(Inquiry model)
    {
        if (ModelState.IsValid)
        {
            db.Inquiries.Add(model);
            db.SaveChanges();
        }
        return Json(model);
    }

Make sure you have referenced the following script in your page:

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

It is what makes the Ajax.* helpers work.
