Images are loaded via AJAX(H) call after you click the container. Lazy Load is applied in the callback.
 $("#container").one("click", function() {
     $("#container").load("images.html", function(response, status, xhr) {
         $("img.lazy").lazyload();
     });              
 });
      <img class="lazy" data-original="img/example.jpg" width="765" height="574">
