Need to do a real click but can't

I'm trying to click the check box with record and playback, on play back the system is not invoked.  I'm trying to have it do a real mouse click, any ideas?  I would like the option to select by Text of the check and the item number.

Telerik.WebAii.Controls.Html.RadListBox listBox = ActiveBrowser.Find.ById<Telerik.WebAii.Controls.Html.RadListBox>("ctl00_cphTracerPage_rcmbTracersTemplate");

            foreach (Telerik.WebAii.Controls.Html.RadListBoxItem lbItem  in listBox.Items)

            {

                bItem.ScrollToVisible();

                lbItem.Click();

                lbItem.Select();

                Log.WriteLine("List Item: " + lbItem.ToString());

            }
