Repeater's Item command event is not firing on linkbutton click
<p>I am having problem with my repeater's OnItemCommand event.
When I click the Link Button, its not firing.
Am I missing any environment variable</p>

<p>ASPX code</p>

<pre><code>&lt;table&gt;
    &lt;!-- repResearchers begin, 0=display name, 1=url --&gt;
    &lt;asp:Repeater ID="repExtResearchers" Runat="server" OnItemCommand="deleteResearcher"&gt;
        &lt;ItemTemplate&gt;
            &lt;tr&gt;
                &lt;td&gt;
                    &lt;a href="&lt;%# ((System.String[])Container.DataItem)[1] %&gt;"&gt;
                    &lt;%# ((System.String[])Container.DataItem)[0] %&gt;&lt;/a&gt;
                &lt;/td&gt;
                &lt;td&gt;
                    &lt;asp:LinkButton ID="lbDelete" runat="server" CommandName="del" 
                    CommandArgument = "&lt;%# ((System.String[])Container.DataItem)[1]%&gt;"
                    OnClientClick="if (!confirm('Are you sure do you want to delelte it?')) return false;"&gt;Delete&lt;/asp:LinkButton&gt;
                &lt;/td&gt;
            &lt;/tr&gt;
        &lt;/ItemTemplate&gt;
    &lt;/asp:Repeater&gt;
&lt;/table&gt;
</code></pre>

<p>CS</p>

<pre><code>protected void deleteResearcher(object sender, RepeaterCommandEventArgs e)
{
    string a;
    lblError.Text = e.CommandArgument.ToString();
    lblError.Visible = true;
}
</code></pre>
