zoom plugin doesn't work if don't have a container

[Richzendy]

If you have this html code:

  <div class="threesixty car">
      <div class="spinner">
          <span>0%</span>
      </div>
      <ol class="threesixty_images"></ol>

The zoom plugin doesn't work, but if you have this code:

<div id="threesixty-container">
  <div class="threesixty car">
      <div class="spinner">
          <span>0%</span>
      </div>
      <ol class="threesixty_images"></ol>
  </div>

The zoom plugin works fine, it's weird and maybe don't have any sense, but in the practice i see this behavior, the container can be:

<section class="container-fluid" id="container">
</section>

Like http://www.360slider.com/plugins.html example.

maybe it's not a bug, but I think this needs to be known in the doc.
