.net easyui datagrid 分页查询不能翻页，点击翻页没有变化

代码位置错了
public ActionResult TestContent(string code,string name,string address)
{
int pageIndex = Request["page"] == null ? 1 : int.Parse(Request["page"]);
int pageSize = Request["rows"] == null ? 10 : int.Parse(Request["rows"]);

        var list1 = (_db.TestContent.Select(s => s)).ToList();
        var query = from t in list1
                    where ((string.IsNullOrEmpty(code) || t.Code.Contains(code))&&(string.IsNullOrEmpty(name) || t.Name.Contains(name)))
                    where (string.IsNullOrEmpty(address) || address.Contains(t.Address)&&address==t.Address)
                    select new
                    {   t.ID,
                        t.Code,
                        t.Name,
                        t.Address,
                       Time=t.Time.ToString("yyyy-MM-dd"),
                        t.Grede
                    }; 
                                var total = query.Count();              
        var list = query.Skip((pageIndex - 1) * pageSize).Take(pageSize).ToList();
        var  data= new{
             total,
             rows =list
        };        
        return Json(data);
    }
