R – handling events of controls (ON USER CONTROL or WEB PART) added during runtime

I used to have some controls added dynamically through runtime on an ASP.NET webpage and was able to handle their events but now I put the code in a user control but it doesnt work. Any idea?

    while (drr.Read())
    {
        LinkButton lnkbtnDownloadFile = new LinkButton();

        //name of the file ---> drr[2]
        lnkbtnDownloadFile.Click += new EventHandler(lnkbtnDownloadFile_Click);
        lnkbtnDownloadFile.Text = drr[2].ToString();

        PlaceHolderQuestions.Controls.Add(lnkbtnDownloadFile);
        PlaceHolderQuestions.Controls.Add(new LiteralControl("<br/>"));
    }


void lnkbtnDownloadFile_Click(object sender, EventArgs e)
{
    if (sender is LinkButton)
        DownloadFile((sender as LinkButton).Text);
}

so when i add a break point at the event handler it doesnt stop
