The correct callback function for this signal would have the following
signature:

void selectActionBin (GtkWidget      *widget,
                      GdkEventButton *event,
                      MY_DATA        *data)

If you want to use the callback as you wrote it, you could use
g_signal_connect_swapped() which will cause the widget and data
pointers to be swapped.
