title: Dynamically change searchable datatable column property
body: <p>I have to change in one function, after the initialization of a datatable, <code>bSearchable</code> property of a column. I need first to enable and then disable it. </p>
  
  <p>I found an example for visibility:</p>
  
  <pre><code>$(document).ready(function() {
      var table = $('#example').DataTable( {
          "scrollY": "200px",
          "paging": false
      } );
  
      $('a.toggle-vis').on( 'click', function (e) {
          e.preventDefault();
  
          // Get the column API object
          var column = table.column( $(this).attr('data-column') );
  
          // Toggle the visibility
          column.visible( ! column.visible() );
      } );
  } );
  </code></pre>
  
  <p>Can something similar be used also in my case? Something like  <code>column.seachable</code>?</p>
