将模型中的项列表传递回控制器

我有这个类作为我的模型

public class Forecast
{
   public List<Test> Tests { get; set; } 
    public TimeGranularities Granularity { get; set; }
    public DateTime StartTime { get; set; }
    public string StartTimeString { get; set; }
    public int StartTimeMonth { get; set; }
    public int StartTimeYear { get; set; }
    public DateTime EndTime { get; set; }
    public string EndTimeString { get; set; }
    public int EndTimeMonth { get; set; }
    public int EndTimeYear { get; set; }
    public List<ForecastItem> ForecastItems { get; set; }
}

这是要测试的类

public class Test
{
    public int Testint { get; set; }
    public decimal Testdec { get; set; }
    public bool Testbool { get; set; }
}

我的 HTTPGET 操作结果在控制器中

[Authorize]
    [HttpGet]
    public ActionResult Index()
    {
        var model = new Forecast
        {
            StartTimeString = DateTime.Now.AddMonths(-1).ToShortDateString(), 
            EndTimeString = DateTime.Now.ToShortDateString(),
            Tests = new List<Test>
            {
                new Test{Testint = 1, Testbool = false, Testdec = 4},
                new Test{Testint = 2, Testbool = true, Testdec = 5},
                new Test{Testint = 3, Testbool = false, Testdec = 6}
            }
        };
        return View(model);
    }

我的观点

@model ......Forecast
@using (Ajax.BeginForm("Index", "Forecast", new AjaxOptions { UpdateTargetId = "ForecastContainer", InsertionMode = InsertionMode.Replace, HttpMethod = "Post", OnSuccess = "calcTotals", LoadingElementId = "LoadingContainer" }))
{
<div>
    <div style="display: table-cell">
        <input type="submit" value="Generate" class="btn btn-default" />
    </div>
</div>
<br />
<div>
    @foreach (var t in Model.Tests)
    {
        @Html.EditorFor(modelItem => t.Testint)
        @Html.EditorFor(modelItem => t.Testbool)
        @Html.EditorFor(modelItem => t.Testdec)
        <br/>
    }
</div>

视图也显示了我想要的东西。 但是当我提交表单并在 POST 操作中检查返回的模型时，结果是控制器，模型。测试不仅不会保存我的更改，而且为空。

我这样做的方式是否正确。

@for (int i = 0; i < Model.Tests.Count(); i++)
    {
        @Html.CheckBoxFor(m => m.Tests[i].Testbool)
        @Html.TextBoxFor(m => m.Tests[i].Testdec)
        @Html.TextBoxFor(m => m.Tests[i].Testint)
    }
