You're not adding your CellRenderer to the column (something the
TreeViewColumn helpfully does automatically). You need something like

column = Gtk.TreeViewColumn("Value")
renderer = Gtk.CellRendererText()
column.pack_start(renderer, True)
column.set_cell_data_func(renderer, cell_data_func)

and so forth
