部分视图中的发布操作未触发

Question

嗨，我还在学习MVC。我有一个要求，其中我的页面带有带有表名的dropdownlist。当用户选择表名称时，将调用部分视图以在DataTable中显示数据。

当前，尝试显示DataTable时出现问题。后动作GetDPUserList()未触发，因此数据未显示。

这就是我所说的局部视图：

$('#ddPatchingAction').change(function () {
        ddPatchingActionValue = $('#ddPatchingAction option:selected').val();
        if (ddPatchingActionValue) {
            $.get("/PatchingBatch/DataTableBatch", function (data) {
                $('#divPatching').html(data);
                $('#batchTable').DataTable();
            });
        }
    });

这是局部视图：

<table id="batchTable" class="table-striped table-responsive">
    <thead>
        <tr>
            <th>Username</th>
            <th>Name</th>
            <th>Email Address</th>
            <th>Is Admin</th>
            <th></th>
        </tr>
    </thead>
</table>

这是控制器：

using System;

using System.Web.Mvc;
using MVCWeb.Models;
using System.Linq.Dynamic;

namespace MVCWeb.Controllers
{
    public class PatchingBatchController : Controller
    {
        // GET: PatchingBatch
        public ActionResult DataTableBatch()
        {
            return PartialView();
        }

        [HttpPost]
        public ActionResult GetDPUserList()
        {
            //server side parameter
            int start = Convert.ToInt32(Request["start"]);
            int length = Convert.ToInt32(Request["length"]);
            string searchValue = Request["search[value]"];
            string sortColumnName = Request["columns[" + Request["order[0][column]"] + "][name]"];
            string sortDirection = Request["order[0][dir]"];

            List<DP_User> userList = new List<DP_User>();
            using (DBModel db = new DBModel())
            {
                userList = db.DP_User.ToList<DP_User>();
                userList = userList.ToList<DP_User>();
                int totalrows = userList.Count();

                //search
                if (!string.IsNullOrEmpty(searchValue))
                {
                    userList = userList.Where(x => (x.Username != null && x.Username.ToString().ToLower().Contains(searchValue)) ||
                    (x.Name != null && x.Name.ToString().ToLower().Contains(searchValue)) ||
                    (x.Email != null && x.Email.ToString().ToLower().Contains(searchValue))).ToList<DP_User>();
                }

                int totalrowsafterfilter = userList.Count();

                //sorting
                if (!string.IsNullOrEmpty(sortColumnName) && !string.IsNullOrEmpty(sortDirection))
                {
                    userList = userList.OrderBy(sortColumnName + " " + sortDirection).ToList<DP_User>();
                }

                //paging
                userList = userList.Skip(start).Take(length).ToList<DP_User>();

                return Json(new { data = userList, draw = Request["draw"], recordsTotal = totalrows, recordsFiltered = totalrowsafterfilter },
                    JsonRequestBehavior.AllowGet);
            }
        }
    }
}

我已在chrome控制台中签入，但没有错误。所以我不确定是什么问题。我的代码有问题吗？请帮忙。谢谢。
