在vbhtml中使用时，自定义助手中缺少TextBoxFor id

Question

我在自定义助手中使用了TextBoxFor控件。并且它不会生成id属性。这是一个已知的问题吗？或者我在自定义助手中做错了什么？我在下面给出了我的代码，

App_Code/customhelper.vbhtml
@Import System.Web.Mvc
@Import System.Web.Mvc.Html
@ModelType EditorVB.DateSettings

@Helper  MyHelper(ByVal page As WebViewPage, ByVal model As EditorVB.DateSettings)
    
    @page.Html.TextBoxFor(Function(x) model.EndDate)

End Helper

Views/index.vbhtml
@ModelType EditorVB.DateSettings
@CustomHelper.MyHelper(PageContext.Page, Model)

DateSettings.vb
Public Class DateSettings
    Public Property EndDate() As DateTime
        Get
            Return m_EndDate
        End Get
        Set(value As DateTime)
            m_EndDate = value
        End Set
    End Property    
    Private m_EndDate As DateTime
