不能让Javascript对象绑定到动作控制器

我似乎无法弄清楚如何让我的Javascript对象绑定到我的模型，这是(据我所知)就像它一样，就属性而言。

首先创建Javascript对象:

var transDetail = new Object();
transDetail.TransactionDetailID = transdetailId;
transDetail.TransactionID = "";
transDetail.Year = new Date().getFullYear();
transDetail.Volume = "";
transDetail.UnitPrice = "";
transDetail.TransferableVolume = "";
transDetail.Credits = "";
transDetail.Shares = "";
transDetail.DollarsPerShare = "";

然后传递给这个javascript函数

function loadTransDetailEditCreate(d, cb, title, transactionDetail) {
    $.ajax(
        {
            url: '/TransactionDetail/LoadEditCreate',
            data: JSON.stringify(transactionDetail),
            dataType: 'json',
            success: function (result) {
                d.html(result);
                CreateEditTransDetail(d, cb, title, transactionDetail);
                d.dialog('open');
            }
        }
    );
}

我已经核实了传输前的year属性填入了2015。

现在模型定义

public partial class TransactionDetail
{
    public int TransactionDetailID { get; set; }
    public int TransactionID { get; set; }
    public int Year { get; set; }
    public Nullable<int> Volume { get; set; }
    public Nullable<int> UnitPrice { get; set; }
    public Nullable<int> TransferableVolume { get; set; }
    public Nullable<int> Credits { get; set; }
    public Nullable<int> Shares { get; set; }
    public Nullable<int> DollarsPerShare { get; set; }
}

和Action定义

public PartialViewResult LoadEditCreate(TransactionDetail transactionDetail)

当我打破第一个东西进入动作时，所有非空的整型都被设置为0，所有可空的都被设置为null。
