checkbox checkchanged event not firing in datalist control
 

I have a checkbox inside a datalist control with Autopostback="True". When a user clicks the checkbox the associated event Handler is not firing.

My code is

In HTML :

         <asp:DataList ID="myDataList" runat="server"  RepeatColumns="1"   RepeatDirection="Vertical" >

               <ItemTemplate>

                   <asp:CheckBox ID="chkid" runat="server" autopostback="True" />

                   <%#"Id " + Container.DataItem("CustomerID")%><br />

                   <%#"Name " + Container.DataItem("ContactName")%>

                   <br />

                   <br />



               </ItemTemplate>

         </asp:DataList>&nbsp;

In Code behind :

Protected Sub myDataList_ItemCreated(ByVal sender As Object, ByVal e As  system.Web.UI.WebControls.DataListItemEventArgs) Handles myDataList.ItemCreated



        Dim alSelectedValues As New ArrayList



        For Each item As DataListItem In myDataList.Items

            'check the item isn't a header or footer

            If e.Item.ItemIndex > -1 Then

                Dim cb As CheckBox = e.Item.FindControl("chkid")

                AddHandler cb.CheckedChanged, AddressOf Me.checkboxclicked



                Dim value As String = cb.Text

                Dim checked As Boolean = cb.Checked

                 If checked Then

                    alSelectedValues.Add(value)

                End If

            End If



        Next

The checkboxclicked event Handler is not firing

Please help
