title: jQuery.fn.dataTableExt bind to specific table
body: <p>I am using the following to implement the custom search and filter on datatables.</p>
  
  <pre><code>    jQuery.fn.dataTableExt.afnFiltering.push(
              function (oSettings, aData, iDataIndex) {
      ....
  </code></pre>
  
  <p>Now everything was fine and dandy, untill I had to implement multiple instances of datatables on the same page. So my question is how do I bind the above search and filter logic to a specific datatable?</p>
  
  <p>PS: <em>I know that the code is for legacy version. But that is a non issue for me atm.</em></p>
