Создайте базовую сетку с помощью плагина MappingJS Mapping и MVC 3

Я искал высокий и низкий и пробовал различные шаблоны, но, похоже, я не могу заставить его работать правильно. Когда-то я получил его на работу, было так много кода, что я понял, что должен быть более простой способ, и теперь он полностью сломан. моя цель... понять основы использования KO Mapping и MVC для загрузки этой сетки.. и, возможно, использовать форму для ее обновления. Я не могу найти примеров, которые работают для моей ситуации. Вот что я сейчас тоже теряю.

Вот мое действие:

public JsonResult List()
    {
        var result = new JsonResult();
        result.Data = _service.GetWeightStats();

        return Json(result, JsonRequestBehavior.AllowGet);
    }

Вот мой класс:

public class WeightStat
{
    public int Id { get; set; }
    [Required]
    public double Weight { get; set; }
    public double? Neck { get; set; }
    public double? Chest { get; set; }
    public double? Bicept { get; set; }
    public double? Waist { get; set; }
    public double? Hip { get; set; }
    public double? Thigh { get; set; }
    public double? Calf { get; set; }
    [Required]
    public DateTime Date { get; set; }
    [Required]
    public string TimeOfDay { get; set; }
    [Required]
    public string DietBehavior { get; set; }

}

Вот моя строка шаблона:

<tbody data-bind='template: {name: "statRowTemplate", foreach: data.Data }'></tbody>

Вот мой шаблон:

<script id="statRowTemplate" type="text/html">
    <tr data-bind="attr: { id: Id }">
            <td><span data-bind="text: Date"></span></td>
            <td><span data-bind="text: TimeOfDay"></span></td>
            <td><span data-bind="text: DietBehavior"></span></td>
            <td><span data-bind="text: Weight"></span></td>
            <td><span data-bind="text: Neck"></span></td>
            <td><span data-bind="text: Chest"></span></td>
            <td><span data-bind="text: Bicept"></span></td>
            <td><span data-bind="text: Waist"></span></td>
            <td><span data-bind="text: Hip"></span></td>
            <td><span data-bind="text: Thigh"></span></td>
            <td><span data-bind="text: Calf"></span></td>
    </tr>
</script>

Вот мой KO JS:

<script type="text/javascript">

var data = $.getJSON('WeightTracker/List');

var viewModel = ko.mapping.fromJSON(data);

ko.mapping.updateFromJSON(viewModel, data);

ko.applyBindings(viewModel);

JSON вернется из действия:

Теперь я предполагаю, что полностью ошибаюсь в этом коде, поскольку я ничего не возвращаю, кроме строки JSON. Я изменил код по-разному, и я работал над этим уже более 2 недель, пытаясь заставить это работать, поэтому, если кто-то может объяснить мне, что я делаю неправильно, отправляю меня на примеры веб-сайта knockoutjs, которые не имеют были полезны. Заранее благодарю вас за помощь и спаси меня от роста еще более седых волос:/

PS. тоже добавьте к этому также. Я хотел бы использовать это mvcextension, которое создал друг, который у меня работал, но я должен был сделать что-то вроде data.WeightStats или что-то еще.. так расстроен:/проверить его

public static MvcHtmlString KnockoutForModel<TModel>(this AjaxHelper<TModel> helper, bool includeScriptTags = true, bool? applyKoBindings = null)
    {
        var serializer = new JavaScriptSerializer();

        var json = "var viewModel = ko.mapping.fromJS(" + serializer.Serialize(helper.ViewData.Model) + ");\r\n";

        if (applyKoBindings.GetValueOrDefault(includeScriptTags))
        {
            json += "ko.applyBindings(viewModel);\r\n";
        }

        if (includeScriptTags)
        {
            json = "<script type=\"text/javascript\">\r\n" + json + "</script>\r\n";
        }

        return MvcHtmlString.Create(json);
    }
