title: Ext JS filtering rendered columns
body: <p>I want to be able to filter on each column of my data. Each time I filter, I use:</p>
  
  <pre><code>addFilter({
  
               dataIndex: 0, //Or 1,2.. depending on the column i want to filter on
               type: 'string', 
               value: value,
  });
  </code></pre>
  
  <p>The problem here is that dataIndex of the column i am filtering on is an Object, so i am essentially filtering on the literal String value of 'Object'. It is Object because in my store, I am storing an Object for each dataIndex, and displaying it with a <code>render</code> function.</p>
  
  <p>Click the header trigger menu, there is a text box i made to type for filter, if you enter any of the letters of the word 'Object', it works. How do I get it to filter the Object's value, not the literal string '<code>Object</code>'</p>
