problem updating value of hidden field

I am dynamically creating a row of elements including a HiddenField. In a client-side function I am updating the value of this HiddenField. its ok till now.

Now a button click causes a postback and the row of dynamically created elements ( including a HiddenField) is recreated. But the value of HiddenField is not restored as it is restored by viewstate, when updated in server-side code.

How can I persist the javascript-updated value of hiddenfield during the postbacks??
