body: <p>When the user selects an "account" we dynamically create a linkbutton with the selected dates.</p>
  
  <p>However, the linkbutton onclick handler doesn't fire when the button is clicked.</p>

  <pre><code>Dim linkBtn As New LinkButton
  linkBtn.Text = "blah"
  AddHandler linkBtn.Click, AddressOf linkButtonHandler
  linkBtn.ID = panelDatesRencontre.Controls.OfType(Of LinkButton).Count
  panelDatesRencontre.Controls.Add(linkBtn)
  ScriptManager1.RegisterAsyncPostBackControl(linkBtn)
  
  Dim Trigger1 As New AsyncPostBackTrigger
  Trigger1.ControlID = linkBtn.ID
  Trigger1.EventName = "Click"
  UpdatePanel2.Triggers.Add(Trigger1)
