SQL server update query not working

Question

I want to edit a Datalist values and update but I can't see why the update procedure does not modify the text. What I have is

Page view

<asp:Panel ID="Panel1" runat="server">
    <div id="DivIntrebare" runat="server" Visible="false">

            </asp:DataList>
        </div>
    </div>
</asp:Panel>

code behind

protected void DataList1_UpdateCommand(object source, DataListCommandEventArgs e)
{
    using (SqlConnection conn = new SqlConnection(connString))
    {
        int id = Convert.ToInt32(DataList1.DataKeys[e.Item.ItemIndex].ToString());
        TextBox txtIntrebare = (TextBox)e.Item.FindControl("txtIntrebare");

        string sqlQuery = "UPDATE tblIntrebare SET Intrebare=@Intrebare WHERE IdIntrebare=@id";
        using (SqlCommand cmd = new SqlCommand(sqlQuery, conn))
        {
            cmd.CommandType = CommandType.Text;
            cmd.Parameters.Add("@id", SqlDbType.Int).Value = id;
            cmd.Parameters.Add("@Intrebare", SqlDbType.NVarChar).Value = txtIntrebare.Text;

            conn.Open();
            cmd.ExecuteNonQuery();
            conn.Close();
        }
        DataList1.EditItemIndex = -1;
        LoadData();
    }
}

So, on update the int id is correct but txtIntrebare is not modified at all
