Please, try to use my pull request to racer. It is working for me for reactive pagination, wanna to know your feelings

My paginator component:

class CardsList_Paginator
    create: (model) ->      
        model.start 'pages', model.scope('_page.cards_count'), model.scope('_session.cards_in_page'), (cards_count, cards_in_page) -> 
            last = Math.ceil cards_count / cards_in_page
            last = 1 if last == 0
            [0..last - 1]
    previousPage: (ev) ->
        page = app.model.get '_session.page_index'
        page -= 1
        page = 0 if page < 0
        @gotoPage ev, page
    nextPage: (ev) ->
        page = app.model.get '_session.page_index'
        page = 1 unless page
        page += 1
        last = @model.get 'pages'
        last = last[last.length - 1]
        page = last if page > last
        @gotoPage ev, page
    gotoPage: (ev, page) ->
        app.model.set '_session.page_index', page
        body = $ "html, body"
        body.animate { scrollTop:0 }, '500', 'swing'
        do ev.preventDefault

and view (bootstrap 3)

paginator:
    ul.pagination(class='{{if !pages || pages.length == 1}}hidden{{/}}')
        li
            a(href="#" aria-label="Previous" on-click='previousPage($event)')
                span(aria-hidden="true") «
        each pages as #page
            li 
                a(href="#" on-click='gotoPage($event, #page)') {{#page + 1}}
        li
            a(href="#" aria-label="Next" on-click='nextPage($event)')
                span(aria-hidden="true") »

May be it is not a best solution, but it is working. Want to know your opinion
