C# – Question concerning asp:listview and multiple dynamically created controls

I have a listview that displays a list of textboxes that get created on a button click. I would also like a label to be created next to each txtbox that would increment what is says from step x: to step x+1:

Do I need to create another listview control for this, or is there a much easier way (which I hope)?

Here is the current web code for my listview:

<tr align="center" valign="middle">
    <td>
        <asp:ListView ID="lvDynamicTextboxes" runat="server" ItemPlaceholderID="itemPlaceholder" onitemdatabound="lvDynamicTextboxes_ItemDataBound">
            <LayoutTemplate>
                <asp:PlaceHolder ID="itemPlaceholder" runat="server" />
            </LayoutTemplate>
            <ItemTemplate>
                <asp:Label ID="lblStep" runat="server" Text="Step 1:" />
                <asp:TextBox ID="txtStep" runat="server" TextMode="MultiLine" Rows="3" Width="300" style="margin-top:10px;" />
            </ItemTemplate>
        </asp:ListView>

        <br /><asp:Button ID="btnAddNewStep" runat="server" Text="Add another step" onclick="btnAddNewStep_Click" style="margin-top:5px;" />
    </td>
</tr>

And here is the code-behind

protected void btnAddNewStep_Click( object sender, EventArgs e )
{
    this.UpdateDataSource();
    this.IncrementTextboxCount();
    this.BindListView();
}

private void BindListView()
{
    //create an enumerable range based on the current count
    List< string > dataSource = this.GetDataSource();

    //bind the listview
    this.lvDynamicTextboxes.DataSource = dataSource;
    this.lvDynamicTextboxes.DataBind();
}

private void IncrementTextboxCount()
{
    List< string > dataSource = this.GetDataSource();

    dataSource.Add( string.Empty );
    this.SetDataSource( dataSource );
}

private List< string > GetDataSource()
{
    List< string > dataSource = null;

    if ( ViewState[ "DataSource" ] != null )
        dataSource = ( List< string > )ViewState[ "DataSource" ];
    else
    {
        dataSource = new List< string >();
        dataSource.Add( string.Empty );
        ViewState[ "DataSource" ] = dataSource;
    }

    return dataSource;
}

private void UpdateDataSource()
{
    List< string > dataSource = new List< string >();

    foreach ( ListViewItem item in this.lvDynamicTextboxes.Items )
        if ( item is ListViewDataItem )
        {
            TextBox txt = (TextBox)item.FindControl( "txtStep" );
            dataSource.Add( txt.Text );
        }

    this.SetDataSource( dataSource );
}

protected void lvDynamicTextboxes_ItemDataBound( object sender, ListViewItemEventArgs e )
{
    if ( e.Item is ListViewDataItem )
    {
        TextBox txt = (TextBox)e.Item.FindControl( "txtStep" );
        txt.Text = ( (ListViewDataItem)e.Item ).DataItem.ToString();
    }
}

private void SetDataSource( List< string > dataSource )
{
    ViewState[ "DataSource" ] = dataSource;
}

EDIT::

Since there seems to be a bit of confusion, I'll try to clarify:

As of now, I have a textbox in a listview with a button underneath.

 ________
| txtbox |
|________|
  _____
 |_btn_|

When you click a button, it generates another text box, so clicking it twice results in this:

 ________
| txtbox |
|________|
 ________
| txtbox |
|________|
 ________
| txtbox |
|________|
  _____
 |_btn_|

These textboxes are to create steps in a process, so all I would like to do is add a generated label next to each generated textbox to say which step it is. So I want it to look like this:

               ________
["Step 1"]    | txtbox |
              |________|
               ________
["Step 2"]    | txtbox |
              |________|
               ________
["Step 3"]    | txtbox |
              |________|
                _____
               |_btn_|

And if they click the button again, then another label is generated with the text "Step 4"
