Change not reflected when using ets:update_counter

[Anindya Mozumdar]

Hi,
    I am using ets:update_counter/3 to update a field in a table which 
has been created as follows :

mnesia:create_table(my_table,[{disc_copies, [node()]},{attributes, 
record_info(fields, my_table)}])

While ets:tab2list/1 confirms that the change has actually taken place, 
it is lost when I stop and start mnesia again ? Is there any way I can 
ensure that the change persists when I stop mnesia ?
Thanks,
Anindya.
