C# DataGridView_RowsAdded event not firing

In a Windows Form I have a datagridview with a bindingsource.
The binding source connects to an external device that adds rows data each 1/20 sec.
Changes of the data are well displayed on the screen (within the datagridview)  but the DataGridView_RowsAdded in the code behind does not fire .
I am unable to understand why.
 
public void dgvvNodes_RowsAdded(object sender, DataGridViewRowsAddedEventArgs e)
        {         
   
            string searchValueLA = "LeftArm";
            int rowIndexLA = -1;
            Node nodeLA;

            foreach (DataGridViewRow row in dgvvNodes.Rows)
            {
                    if (dgvvNodes.Rows[e.RowIndex].Cells[5].ToString().Equals(searchValueLA)) // "position" is at index 5 in the last added row
                    {
                        rowIndexLA = row.Index;
                        nodeLA = dgvvNodes.Rows[e.RowIndex].DataBoundItem as Node; // get the object origin of data in the last added row 
                        break;
                    }
            }
}

I believe the rows_added event is only fired when u manually add a row. via the gridview...

the DataBound is the only event that will be able to tell when rows are added by keeping a count of previous rows.
