Ajax Action不刷新页面

Question

我有以下问题，我想刷新一个asp.mvc控件。

<table>
    <tr>
        <td>Rolle</td>
        <td>
        <div>
            @Html.Telerik().ComboBox().Name("DdlRoleAuthority").SelectedIndex(-1).BindTo(Model.RoleList)
             </div>       
        </td>
    </tr>
    <tr>
        <td valign="top">Programme</td>
        <td>
            <div style="width:240px;height:160px;color:White;">
               @Html.CheckBoxListFor(model => model.AuthorityRoles, Model.AuthorityRoleList)
            </div>
        </td>
    </tr>
</table>

我有一个Telerik Combobox，当它被更改时，我想刷新Checkbox列表。 javascript是

$(document).ready(function () {
    alert('a1');
    $('#DdlRoleAuthority').bind('valueChange', function(e) {
        onRoleAuthorityChange(e.value); 
    });
}

function onRoleAuthorityChange(e) {
    alert('0');
    var userId =document.getElementById('CurrentID').value;
    $.ajax({
        url: '@Url.Action("RoleListIndexChanged", "User")',
        type: 'get',
        dataType: 'html',
        data: {roleId: e, userId : userId},
        success: function(data) 
        {                 
            $('#AuthorityRoles').dataBind(result);
        }

     });
     alert('1');
 }

行动是

public ActionResult RoleListIndexChanged(int? roleId, int? userId)
{
    UserSettingsViewModel result = CreateSettingsViewModel(userId.Value, roleId);
    return PartialView(result.AuthorityRoleList);
}

我该怎么办，以便刷新CheckboxList？

复选框列表是

public static MvcHtmlString CheckBoxListFor<TModel, TProperty>(this HtmlHelper<TModel> htmlHelper, Expression<Func<TModel, TProperty[]>> expression, MultiSelectList multiSelectList, object htmlAttributes = null)         
{         
    MemberExpression body = expression.Body as MemberExpression;             
    string propertyName = body.Member.Name;            
    TProperty[] list = expression.Compile().Invoke(htmlHelper.ViewData.Model);                           
    List<string> selectedValues = new List<string>();              
    if (list != null)             
    {                
        selectedValues = new List<TProperty>(list).ConvertAll<string>(delegate(TProperty i) { return i.ToString(); });             
    }

    TagBuilder divTag = new TagBuilder("div");             
    divTag.MergeAttributes(new RouteValueDictionary(htmlAttributes), true);                        
    foreach (SelectListItem item in multiSelectList)             
    {                 
        divTag.InnerHtml += string.Format(
            "<div><input type=\"checkbox\" name=\"{0}\" id=\"{0}_{1}\" " +                                                     
            "value=\"{1}\" {2} /><label for=\"{0}_{1}\">{3}</label></div>",                                                     
            propertyName,                                                     
            item.Value,                                                    
            selectedValues.Contains(item.Value) ? "checked=\"checked\"" : string.Empty,                                                     
            item.Text);             
    }

    return MvcHtmlString.Create(divTag.ToString());         
}
