C# asp.net why does my manual __doPostBack only run once?
<p>In my code I create the menu items dynamically:</p>

<pre><code>string listClientID = BulletedList1.ClientID.Replace('_', '$');
int counter = 0;

foreach (DataRow dataRow in database.DataTable.Rows)
{
    // Add Button
    ListItem listItem = new ListItem();
    listItem.Value = "buttonItem" + Convert.ToString(dataRow["rank"]);
    listItem.Text = " " + Convert.ToString(dataRow["title"]);
    listItem.Attributes.Add("onclick", "__doPostBack('" + listClientID + "', '"+ counter.ToString() +"')");

    BulletedList1.Items.Add(listItem);

    counter++;

}
</code></pre>

<p>This menu is inside a update panel:</p>

<pre><code>&lt;div id="MenuItemBox"&gt;
    &lt;asp:BulletedList 
        ID="BulletedList1" 
        runat="server"
        OnClick="MenuItem_Click"
        &gt;
    &lt;/asp:BulletedList&gt;
&lt;/div&gt;
</code></pre>

<p>What I want is when a listitem is clicked it performs a postback. But when I run this, the onclick event is only runned once. </p>

<p>For example. I have 4 listitems. When I click the first item the first time the onclick event is executed. Now I click the second item, the onclick event is also executed. But when I now click the first item again the onclick event is not fired.</p>

<p>When I check the error console in FireFox or Oprah I don't get any errors.</p>

<p>So my question is: how can I fix this and what am I doing wrong?</p>
