title: Add DOM elements on Datatables wrapper
body: <p>My aim is to add buttons on a table created by datatables.js on its header.
  My code to add buttons is:</p>
  
  <pre><code>$('#myButton').prependTo($('#myTable_wrapper'));
  </code></pre>
  
  <p>The problem is i can't find the right timing to add the button. I have tried adding the button right after the table was created but it seems like the wrapper is not yet created at that moment.
  I also tried adding the button on $(document).ready() but the wrapper is also not yet  created at that part of the code.</p>
  
  <pre><code>$(document).ready(function () {
    $("#myTable").datatables();
    $('#myButton').prependTo($('#myTable_wrapper'));
  });
  </code></pre>
  
  <p>Where is the right part of the code to modify the wrapper?</p>
