Datatables doesn't recognize pageLength for number of rows
<p>I'm simply trying to have only 15 rows when I bring my data up. For some reason it is not working. Any help would be appreciated.</p>

<pre><code>    $('.datatable').dataTable({
    "processing": true,
    "serverSide": true,
    "ajax": {
        "url": "/ajaxI/gd/1/54",
        "data": function (d) {

        }
    },
    "paging": true,
    "searching": false,
    "lengthChange": true,
    "lengthMenu": [[15, 25, 50, -1], [15, 25, 50, "All"]],
    "pageLength": 15,
    "oLanguage": {
        "sProcessing": ' &amp;nbsp; &lt;img src="/img/ajax-loader-large.gif" alt="Loading" width="26" height="26" /&gt;'
    },
    "autoWidth" : false        }
});
</code></pre>

<p>All my data shows up for some weird reason.</p>
