Here I can use Set and get methods or different method will be there. How to implement this?

Ruby has attr_* for getters and setters:

Well, you're not going to be doing this in Ruby, since HTTP is stateless. Since you're using AJAX, you might as well store your entire resultset as JS, and fetch each page from your local collection. That said, maybe you should look at Mislav will_paginate (http://github.com/mislav/will_paginate). Sure, you'll hit the DB for each page, but it's simple to implement, it's well tested and it performs reasonably well.
