title: How dynamically change column title of dataTable jQuery plugin?
body: <p>I would like to change the title of a column  my datatable generated by jQuery Datatable plugin</p>
  
  <p>Do you know if I can do something like this:</p>
  
  <pre><code> table = $('#example').DataTable({
          "data": source_dataTable,
          "columnDefs": defs,
  
      "dom": 't&lt;"top"f&gt;rt&lt;"bottom"lpi&gt;&lt;"clear"&gt;',
  });
  // WHAT I WANT TO DO:
      table.column(0).title.text("new title for the column 0")
  </code></pre>
  
  <p>?</p>
  
  <p>It renders a html a first line like that:</p>
  
  <pre><code> &lt;table id="example" class="row-border hover dataTable no-footer" role="grid" aria-describedby="example_info" style="width: 1140px;"&gt;
     &lt;thead&gt;
         &lt;tr role="row"&gt;
                &lt;th class="sorting" tabindex="0" aria-controls="example" rowspan="1" colspan="1" aria-label="S&amp;amp;#233;lectionn&amp;amp;#233;: activer pour trier la colonne par ordre croissant" style="width: 94px;"&gt;Sélectionné&lt;/th&gt;
  
                 &lt;th class="sorting" tabindex="0" aria-controls="example" rowspan="1" colspan="1" aria-label="Anglais : activer pour 
  
                    trier la colonne par ordre croissant" style="width: 
  
  62px;"&gt;Anglais &lt;/th&gt;
  
  &lt;/tr&gt;
  &lt;/thead&gt;
   &lt;/table&gt;
  </code></pre>
  
  <p>...</p>
  
  <p>In a normal table the code bellow work , but for datatable rendered by jQuery plugin, it doesn't:</p>
  
  <pre><code>$('#example tr:eq(0) th:eq(0)').text("Text update by code");
  </code></pre>
  
  <p>Maybe there is a API method or another dom way?</p>
