I believe the best way is to add an integer column to the list store and
use 'set_cell_data_func' as follows to set the row number to update
automatically after whatever changes in the list store.

def set_row_number(column, renderer, store, itr):
    renderer.props.text = store.get_path(itr)[0] + 1
column.set_cell_data_func(renderer, set_row_number)
