Ajax.BeginForm没有发布到控制器操作

Question

我正在尝试使用Ajax.BeginForm将我的视图发回控制器，但它无法正常工作。我已尝试在stackoverflow上发布了一些建议，但它们都不起作用。以下是我的代码。

//视图

@using(Ajax.BeginForm("Index", "fundcode", new AjaxOptions() {  HttpMethod = "POST" }))
    {
        @Html.AntiForgeryToken()

        <div class="form-group">
            <div class="input-group">
                @Html.HiddenFor(model => model.Id)

                @Html.LabelFor(model => model.FundLocal, htmlAttributes: new { @class = "input-group-addon", @style = "font-weight: bold;" })
                @Html.EditorFor(model => model.FundLocal, new { htmlAttributes = new { @class = "form-control" } })
            </div>
            <label class="text-danger pull-right">@Html.ValidationMessageFor(model => model.FundLocal)</label>
        </div>

        <br />

        <div class="form-group">
            <div class="input-group">
                @Html.LabelFor(model => model.FundEnglish, htmlAttributes: new { @class = "input-group-addon", @style = "font-weight: bold;" })
                @Html.EditorFor(model => model.FundEnglish, new { htmlAttributes = new { @class = "form-control" } })
            </div>
            <label class="text-danger pull-right">@Html.ValidationMessageFor(model => model.FundEnglish)</label>
        </div>

        <br />

        <div class="form-group">
            <div class="input-group">
                @Html.LabelFor(model => model.FundCode1, htmlAttributes: new { @class = "input-group-addon", @style = "font-weight: bold;" })
                @Html.EditorFor(model => model.FundCode1, new { htmlAttributes = new { @class = "form-control" } })
            </div>
            <label class="text-danger pull-right">@Html.ValidationMessageFor(model => model.FundCode1)</label>
        </div>

        <br />

        <div class="form-group">
            <input type="submit" id="btnSave" value="ثبت" class="btn btn-primary btn-flat col-lg-2 col-md-2 col-sm-2 col-xs-12 pull-right" />
        </div>
    }

//控制器操作

   [HttpPost]
        public ActionResult Index(Models.FundCode fundcode)
        {
            if (ModelState.IsValid)
            {
                var db = new Models.FAPEntities();

                if (fundcode.Id == null)
                {
                    fundcode.InsertDate = DateTime.Now;
                    fundcode.InsertedBy = 1;
                    fundcode.UpdatedBy = 0;
                    fundcode.DeletedBy = 0;

                    db.FundCodes.Add(fundcode);
                }
                else
                {
                    var record = db.FundCodes.Find(fundcode.Id);

                    if (record != null)
                    {
                        record.UpdateDate = DateTime.Now;
                        record.FundLocal = fundcode.FundLocal;
                        record.FundEnglish = fundcode.FundEnglish;
                        record.FundCode1 = fundcode.FundCode1;
                        record.UpdatedBy = 1;
                    }
                }

                db.SaveChanges();
            }

            ActivateTab(classes.ActiveTab.AddTab);

            ViewBag.FundCodes = new Models.FAPEntities().FundCodes.Where(f => f.DeletedBy == 0).OrderByDescending(f => f.Id).ToList();
            return View();
        }

//模型
