Datagrid is not saving the changes user applies

I'm having troubles in getting a grid to work:

I want to let users add rows but when the program is compiled the CanUserAddRows is set to false. - SOLVED

Another problem I'm facing is when the user edits the grid, it isn't applying what has been changed; although the delete is working fine.

How can I solve this? 

public ObservableCollection<BolaInfo> bolas;
public IniciaSim()
{
    this.InitializeComponent();
    this.bolas = new ObservableCollection<BolaInfo>();
}

private void Introduzir_Click(object sender, RoutedEventArgs e)
{
    if (rendering)
    {
        plotCanvas.Children.Clear();
        CompositionTarget.Rendering -= RenderFrame;
        rendering = false;
    }

    DataGrid dados = new DataGrid();
    dados.Width = plotCanvas.ActualWidth;
    dados.Height = plotCanvas.ActualHeight;
    dados.ColumnWidth = 128;
    dados.IsReadOnly = false;
    dados.IsEnabled = true;
    dados.AutoGenerateColumns = true;
    dados.CanUserResizeColumns = false;
    dados.CanUserReorderColumns = false;
    dados.CanUserAddRows = true;
    dados.CanUserDeleteRows = true;
    dados.ItemsSource = bolas;
}

Check if BolaInfo class has a contructor without parameters. I think you can only add rows automatically if the class can create a new instance without parameters.
