Ajax LoadMore Pagination Button for Jekyll (https://eduardoboucas.com/blog/2014/11/05/adding-ajax-pagination-to-jekyll.html)

blog.html

<div class="wrap">
  <div id="container" class="wrap-inner" data-page="{{ currentPage }}" data-totalPages="{{ paginator.total_pages }}">

    {% assign posts = site.posts | where: "language", page.language %}

    {% if paginator.page %}
      {% assign offset = paginator.page | minus:1 | times:paginator.per_page %}
      {% assign currentPage = paginator.page %}
    {% else %}
      {% assign offset = 0 %}
      {% assign currentPage = 1 %}
    {% endif %}

    {% for post in site.posts limit:site.paginate offset:offset %}
    <article class="post entry" itemscope itemtype="http://schema.org/CreativeWork">

      <header class="entry-header">
        <h2 class="entry-title" itemprop="headline"><a href="{{ post.url }}" rel="bookmark">{{ post.title }}</a></h2>
        <p class="entry-meta">
          <time class="entry-time" itemprop="datePublished" datetime="{{ post.date | date_to_xmlschema }}">{% include post-time.html %}</time>
        </p>
      </header>

      <div class="entry-content" itemprop="text">
        <a href="{{ post.url }}" aria-hidden="true">
          <div class="post-image">
            <img width="756" height="300" src="{% if post.featured_image_path %}{{ post.featured_image_path }}{% else %}/images/default.jpg{% endif %}" alt="{{ post.title }}" itemprop="image">
          </div>
        </a>
        <p>{{ post.content | strip_html | truncatewords: 60 }}</p>
      </div>

    </article>
    {% endfor %}

    {% assign postCount = site.posts | size %}
    {% assign postsCovered = site.paginate | plus:offset %}
    {% if postsCovered < postCount %}
      <button id="loadmore" class="button loadmore">Load more posts</button>
    {% endif %}

  </div>
</div>

pagination.js

$("#loadmore").click(loadMorePosts);

function loadMorePosts() {
  var _this = this;
  var $container = $("#container");
  var nextPage = parseInt($container.attr("data-page")) + 1;
  var totalPages = parseInt($container.attr("data-totalPages"));

  $(this).addClass("loading");

  $.get("/blog/page" + nextPage, function (data) {
    var htmlData = $.parseHTML(data);
    var $articles = $(htmlData).find("article");

    $container.attr("data-page", nextPage).append($articles);

    if ($container.attr("data-totalPages") == nextPage) {
      $("#loadmore").remove();
    }

    $(_this).removeClass("loading");
  });
}

I'm trying to get this to work for multiple languages, but since the paginate plugin won't output the pages for more than one language it's not working. Any advice on getting pagination or a "load more" option to work for multi-language sites would be very welcome.
