How to Retain Dynamically created rows on coming back to a page

[Aseem]

I have dynamically inserted rows in a table using - insertRow().
When i return to the page using the Back button - the rows inserted using
insertRow() do not appear, though using the same function retrives the data
, the objects (if any) and the rows. How can i make these rows persist so
they appear on clicking of the Back button.
