Dynamically adding content to ToolTipManager

[judo]

I'm not sure where I am going wrong with this, but I just want to dynamically add some text to a literal when the Tooltip is activated.

My aspx code is :

<asp:Image ID="helpImg" runat="server"    ImageUrl="~/images/help4.gif" />
<telerik:RadToolTipManager ID="RadToolTipManager1" runat="server"
    OnAjaxUpdate="OnAjaxUpdate"  Width="250" Height="175" HideEvent="ManualClose"
    ShowEvent="OnClick" Skin="Hay">
<TargetControls>
<telerik:ToolTipTargetControl  TargetControlID="helpImg"  />
</TargetControls>
</telerik:RadToolTipManager>

The code behind is:

    Protected Sub OnAjaxUpdate(ByVal sender As Object, ByVal args As ToolTipUpdateEventArgs)
        Dim textLit As New Literal
        textLit.Text = "texteexttext"
        RadToolTipManager1.TargetControls.Add(textLit.ID)
    End Sub

Not sure where I am going wrong...

Thx
