从Ajax表单加载的MVC4 WebGrid - 在排序和分页时多次调用Controller

I have the following in my view

我认为我有以下几点

@using (Ajax.BeginForm("Search", "Home", null,
                               new AjaxOptions
                                   {
                                       InsertionMode = InsertionMode.Replace,
                                       HttpMethod = "POST",
                                       UpdateTargetId = "gridContent",
                                   }, new { @class = "search" }))
{
    <input type="submit" value="Search" />
}
<div id="gridContent">
</div>
