title: How to change defaults for a jquery DataTables plugin
body: <p>I'm trying to set the defaults for the datatables I use in my project.</p>
  
  <p>I can change dataTables defaults with:</p>
  
  <pre><code>$.extend($.fn.dataTable.defaults.oLanguage, {
      "sProcessing": "Loading..."
  });
  </code></pre>
  
  <p>But when I try to change a default for a plugin value, like:</p>
  
  <pre><code>$.extend($.fn.dataTable.defaults.oColVis, {
      "buttonText": "Change columns"
  });
  </code></pre>
  
  <p>It doesn't works.</p>
  
  <p>I tried to find the defaults used by the plugin in <code>$.fn.dataTableExt</code> but couldn't find anything.</p>
  
  <p>EDIT: just to be sure I made myself clear in my question, I know that I can change plugins properties in the dataTable initialization, as <a href="https://stackoverflow.com/users/397861/nicola-peluchetti">Nicola Peluchetti</a> pointed out.</p>
  
  <p>But I use the dataTable in different places in my project and I would have to repeat the code in various places that way. Not an option.</p>
