I have been struggling with this for days. I have a form that’s a partial view loaded via Ajax but it’s not submitting via Ajax even though it uses Ajax.BeginForm().

Controller:

<HttpGet()> _
    Public Function PersonalDetailsEdit(PersonalInfo As DetailsViewModel.PersonalDetails) As PartialViewResult
        Return PartialView(PersonalInfo)
    End Function

    <HttpPost()> _
    <AjaxOnly()> _
    Public Function PersonalDetailsEdit(formcollection As FormCollection, model As DetailsViewModel.PersonalDetails) As PartialViewResult
        Return PartialView("PersonalDetails", model)
    End Function

View:

@ModelType ASK.Everest.ViewModels.DetailsViewModel.PersonalDetails

@Using Ajax.BeginForm("PersonalDetailsUpdate", "Details", New AjaxOptions() With {
                     .InsertionMode=InsertionMode.Replace,
                     .UpdateTargetId = "PersonalDetailsSection",
                     .OnFailure = "alert('fail');"}, New With {.id="PersonalDetailsForm"})
    @Html.ValidationSummary(True)

@<fieldset id="PersonalDetailsUpdate">
    <table class="table table-striped ">
        <tr>
            <th class="display-label">
                <input type="hidden" value="@Html.NameFor(Function(model) model.Title)" />
                @Html.DisplayNameFor(Function(model) model.Title)
            </th>
            <th class="display-label">
                <input type="hidden" value="@Html.NameFor(Function(model) model.FirstName)" />

End Using

My bundles:

bundles.Add(New ScriptBundle("~/bundles/ask").Include(
                "~/Scripts/jquery-1.7.*",
                "~/Scripts/jquery-ui*",
                "~/Scripts/jquery.validate*",
                "~/Scripts/jquery.unobtrusive*",
                "~/Content/bootstrap/js/bootstrap.js"))

_Layout.vbtml:

<!DOCTYPE html>
<html lang="eng">
<head>
    <meta charset="utf-8" />
    <meta name="viewport" content="width=device-width" />
    <title>@ViewData("Title")</title>
    @Styles.Render("~/Content/css")
    @RenderSection("styles", required:=False)

    @Scripts.Render("~/bundles/modernizr")
    @Scripts.Render("~/bundles/ask")

    @RenderSection("scripts", required:=False)
</head>
<body>
    @RenderBody()
</body>
</html>

Gave up after much frustration and decided to go JQuery + Knockout route with MVVM on the client side like this:

<script type="text/javascript">
var data = @Html.Raw(Json.Encode(Model)) ;
var PersonalDetailsVM = ko.mapping.fromJS(data);
ko.applyBindings(PersonalDetailsVM, $('section#PersonalDetails')[0]);
</script>

Now I’m just struggling with JSON/MVC Date conversions – I thought MVC4 was supposed to use JSON.NET by default? I’ll just post another question if it’s a lot of hassle.
