phalcon paginator paging not working in partial view, called from Ajax.

Hi, if it can help, here is a paste of how I'm doing this (using previous/next button, instead of the link provided by volt):

    (initial html )
    <div class="liste-commandes-pager">
        <div class="col-md-4 no-padd-no-margin">
            <button class="btn-navig btn-previous-page" data-page="1">previous page</button>
        </div>
        <div class="col-md-4 no-padd-no-margin">
            <div class="col-md-4 no-padd-no-margin">
                <button class="btn-navig btn-first-page" data-page="1">first  page</button>
            </div>
            <div class="col-md-4 no-padd-no-margin">
                <button class="btn-navig btn-navig-info"></button>
            </div>
            <div class="col-md-4 no-padd-no-margin">
                <button class="btn-navig btn-last-page" data-page="0">last page</button>
            </div>
        </div>
        <div class="col-md-4 no-padd-no-margin">
            <button class="btn-navig btn-next-page" data-page="2">next page </button>
        </div>

    </div>

javascript

    (js)
      $('.btn-previous-page, .btn-first-page').on('click', function (e) {
            e.preventDefault();
            var pageNumber = $(this).data('page');
            getpagedCommandes('BC', pageNumber, "previous");
       });
      $('.btn-next-page, .btn-last-page').on('click', function (e) {
          e.preventDefault();
          var pageNumber = $(this).data('page');
          getpagedCommandes('BC', pageNumber, "next");
      });

      ....

     //the ajax call, note that button's html is updated on reponse
    function getpagedCommandes(type, pageNumber, direction) {
    $.ajax({
        type: "POST",
        dataType: 'json',
        data: {
            type: type,
            page: pageNumber
        },
        cache:false,
        headers: {'HTTP_X_REQUESTED_WITH': 'XMLHttpRequest'},
        url: serveurAdress + '/pieces/commandesJson',
        complete: function (response) {
            rep = jQuery.parseJSON(response.responseText);

                    $('.btn-last-page-liv').attr('data-page', pageCount);

                    switch(direction) {
                        case "next":
                            if(pageNumber !== pageCount) {
                                $('.btn-previous-page').css('display', 'block').data('page', pageNumber-1);
                                $('.btn-next-page').data('page', pageNumber+1);
                            }
                            else {
                                $('.btn-previous-page').css('display', 'block').data('page', pageNumber-1);
                                $('.btn-next-page').css('display', 'none');
                            }
                            break;
                        case "previous":
                            if(pageNumber !== 1) {
                                $('.btn-previous-page').css('display', 'block').data('page', pageNumber-1);
                                $('.btn-next-page').data('page', pageNumber+1);

                                $('.btn-next-page').css('display', 'block').data('page', 2);
                            }
                            break;
                        }

                    $('.btn-navig-info').text(pageNumber + "/" +pageCount);

        }
    });
}
