How to create dynamic control and not use the selectedindexchanged

[mamataingle]

My code is not working on selectedindexchanged on dynamic radiobuttonlist control

public void data1()


        {


        Table tbldynamic = new Table();
        for (int i = 0; i < 4; i++)
        {
            connection = new DAL_Layer();
            dt = new DataTable();
            dsCommonData = connection.returnDataSet("pro");
            dt = dsCommonData.Tables[i];

            TableCell tc1 = new TableCell();
            TableRow tr1 = new TableRow();
            RadioButtonList rdn = new RadioButtonList();
            rdn.ID = "rdn" + i;
            rdn.Text = "rdn" + i;

            // DataRowView dr = e.Row.DataItem as DataRowView;
            rdn.SelectedValue = dt.Rows[0]["name"].ToString();
            rdn.SelectedIndexChanged+= new EventHandler(rbl_SelectedIndexChanged);
            //rdn.AutoPostBack = true;
            rdn.DataSource = dt;
            rdn.DataTextField = "name";
            // checkbox.DataValueField = "id";
            rdn.DataBind();
            tc1.Controls.Add(rdn);
            tr1.Cells.Add(tc1);

            tbldynamic.Rows.Add(tr1);
        }
        panel2.Controls.Add(tbldynamic);
    }

      protected void rbl_SelectedIndexChanged(object sender, EventArgs e)
    {
        for (int i = 0; i < 4; i++)
        {
            RadioButtonList c = (RadioButtonList)panel2.FindControl("rdn");
            lblid.Text = c.SelectedItem.Text;
        }
    }
