How to add multiple timer in a list without refreshing the list
===

I have a list which initially contain one item and a 30 sec timer.After 10 second one more item is attached in the list with one 30 second timer.But When I am trying to do this my first timer value  also get refreshed(i.e it starts again from 30 sec).I want that the whole list should not be refreshed.
Any help will be appreciated.
Thanks in advance.
