You can try this ….

<Window x:Class="BindToAdoDataDemo.Window1"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation">http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    Title="Window1" Height="300" Width="300">
  <DockPanel>
    <Button Width="120" Height="30" Content="Add" Name="btn" DockPanel.Dock="Top"/>
    <ListBox ItemsSource="{Binding}" DisplayMemberPath="ChildItem"/>
  </DockPanel>
</Window>

public partial class Window1 : Window
{
    public Window1()
    {
        InitializeComponent();
        DataTable dataTable = MakeChildTable();
        this.DataContext = dataTable.Rows;
        this.btn.Click += delegate
        {
            DataRow row = dataTable.NewRow();
            row["childID"] = 50;
            row["ChildItem"] = "ChildItem " + 50;
            dataTable.Rows.Add(row);    
        };
    }

    private DataTable MakeChildTable()
    {
        DataTable table = new DataTable("childTable");
        DataColumn column;
        DataRow row;

        column = new DataColumn();
        column.DataType = System.Type.GetType("System.Int32");
        column.ColumnName = "ChildID";
        column.Caption = "ID";

        table.Columns.Add(column);

        column = new DataColumn();
        column.DataType = System.Type.GetType("System.String");
        column.ColumnName = "ChildItem";
        column.Caption = "ChildItem";
        table.Columns.Add(column);

        for (int i = 0; i <= 4; i++)
        {
            row = table.NewRow();
            row["childID"] = i;
            row["ChildItem"] = "Item " + i;
            table.Rows.Add(row);
        }

        return table;
    }
}
