$(".videos") .append("

• 
  div class="videos_image"
  a href="pagevideo/"img src="/media/images/" + data.image + " width="250" height="180" / /a
  div
  div class="videos_title"> " + data.title + "div
  div class="videos_views" p Views:" + data.views" p div
  li
  ul

Use a debugger to see how your code works.

$(window).scroll(function(){
    debugger;
