Can you add runat="Server" tag there?

The current work is in client side;
It will not work if i add runat="server" tag

It will - it will still render client side, but it will give server access as well.

If you want to access the controls on the server side for any calculation, you have to mark the controls as 'runat=server'.

Based on the change, you surely have to change the Javascript code too. Current implementation is based on client side html controls, but once you add the runat property to the controls, the way to access them will change. Use <%= myControl.ClientID %> to access the control on client side in JavaScript after the change.
