为什么ajax GET请求只对foreach循环中的第一项有效?

如果用户想要'编辑'事务，我试图用先前输入的数据填充'事务模型'表单。事务作为IEnumerable<Transaction>被传递到视图中。我在一个表中显示每个事务，每行包含一个事务和可以对其执行的操作。一旦用户单击编辑，我已经设置了一个模态弹出与表单内部。为了填充表单，我在每次用户单击edit时创建了一个jquery GET请求，该请求从数据库检索事务并返回我想要的json数据属性。问题是此请求适用于IEnumerable中的第一个事务。

这是我的视图:

<div class="row">
    <div class="col-sm-12">
        <table class="table table-bordered table-hover" cellspacing="0" width="100%" id="TransactionTable">

视图下面的Javascript:

@section page{
    <script src="//cdn.datatables.net/plug-ins/1.10.7/integration/bootstrap/3/dataTables.bootstrap.js"></script>
    <script src="/Scripts/jquery-ui.min.js"></script>
    <script src="/Scripts/bootstrap-datepicker.js"></script>
    <script type="text/javascript">
        $('#editform').click(function (e) {
            $.ajax({
                type: 'GET',
                url: '/Transaction/EditTransactionInfo/',
                dataType: 'json',
                contentType: 'application/json',                
                data: { transId: $("#editform").data('transaction-id') },
                success: function (data) {
                    alert(data.Description);
                }
            })
        })
        $('#TransactionTable').DataTable();
        $('#datepicker1').datepicker();
    </script>
}

和我的请求控制器动作:

[HttpGet]
public JsonResult EditTransactionInfo(int transId)
{
    var trans = db.Transactions.Find(transId);
    return Json(new { Description = trans.Description,
                      Amount = trans.Amount,
    }, JsonRequestBehavior.AllowGet);
}
