I need server-side to know what client-side is doing in real time 
when the user clicks next page.

No.

There's no accessibility problem without js in my current 
investigation. What I'm doing is rather trivial and not necessary for 
the basic operation. It's progressive enhancement, not really needed.

What fun is there in that?

When current technology doesn't fill the bill or is illusive, then 
you must look deeper.
