call retrieve function in paulirish/infinite-scroll
<p>I want to manually trigger the next page load in paulirish/infinite-scroll. I found a function called  </p>

<pre><code>retrieve: function infscr_retrieve(pageNum) {
} 
</code></pre>

<p>I tried to call it directly using something like this.</p>

<pre><code>    var contentScroll = $('#content');
    contentScroll.infinitescroll({
       //bla...........
    });

contentScroll.infinitescroll.retrieve(2);
</code></pre>

<p>error retrieve is not a function. 
Anyone know how I could go about calling this method. </p>
