title: JQuery Datatables not searching by hidden value
body: <p>I have a datatable that contains inputs of type hidden that is in the first td element.</p>
  
  <p>The problem when I type the value in the search bar it doesn't pick it up. It works fine on my local computer, but on the live version it doesn't work. </p>
  
  <p>I checked several times and all the code is exactly the same. All the other functions of the datatable works perfectly. It searches fine on the visible values.</p>
  
  <p>Here is an example. If i search for the hidden value '12345' it wont work on live:</p>
  
  <pre><code>&lt;table id="merchant-table" class="table table-striped table-bordered table-hover"&gt;
          &lt;thead&gt;
              &lt;tr&gt;
                &lt;th&gt;Name&lt;/th&gt;
                &lt;th&gt;Surname&lt;/th&gt;
              &lt;/tr&gt;
          &lt;/thead&gt;
          &lt;tbody&gt;
               &lt;tr&gt;
                 &lt;td&gt;John&lt;/td&gt;
                 &lt;td&gt;Doe &lt;input type='hidden' value='12345'/&gt;&lt;/td&gt;
               &lt;/tr&gt;
          &lt;/tbody&gt;
  &lt;/table&gt;
  </code></pre>
  
  <p>Any ideas?</p>
