title: jQuery datatable sort and order from selected option column
body: <p>I have a jquery datatable and I need to filter and sort inside a cell that contains html select inputs by the text in the selected option <code>&lt;select&gt;&lt;option selected="selected"&gt;**text to filter**&lt;/option&gt;&lt;/select&gt;</code>.</p>
  
  <p>So I need to search the rows in the table that contain a td that contains a select box where I've selected the option with the text used for the search.</p>
  
  <p>So if in a cell I choose the option with <strong>"text to filter"</strong> text that row must be visible.
  Is it possible? How can I do it?</p>
  
  <p>Thank you</p>
