Without calling bindingSource1.EndEdit your underlying DataTable doesn't see any change and thus the Update command has nothing to update.

private void dataGridView1_CellEndEdit(object sender, DataGridViewCellEventArgs e)
{
    bindingSource1.EndEdit();
    DataTable dt = (DataTable)bindingSource1.DataSource;

    // Just for test.... Try this with or without the EndEdit....
    DataTable changedTable = dt.GetChanges();
    Console.WriteLine(changedTable.Rows.Count);

    int rowsUpdated = da.Update(dt);    
    Console.WriteLine(rowsUpdated);
}
