Ok, I’m having issues targeting my newly created DataGrid.

```auto

// try dataGrid
		trace(grid);
		grid.createClassObject(mx.controls.DataGrid, "my_dg", 15, {columnNames:["name", "score"]});
		grid.my_dg.setSize(140, 100);
		grid.my_dg.move(0, 0);
		trace(grid.my_dg);

```

So this doesn’t work - anyone know why?
