title: How SlickGrid invalidates/removes rows
body: <p>I have a custom formatter that listens to mouse clicks. Works perfectly. But i am in doubt with memory leak case since i know the listener must be removed by invoking "off", or the cell container must be removed by invoking empty().remove().</p>
  
  <ol>
  <li>Is SlickGrid aware of that?</li>
  <li>Will the same method be using during refresh operation. I mean will it remove and re-append the rows?</li>
  <li>Is there a memory leak (DOM) at <a href="https://github.com/mleibman/SlickGrid/blob/master/slick.grid.js#L1555" rel="nofollow">https://github.com/mleibman/SlickGrid/blob/master/slick.grid.js#L1555</a></li>
  </ol>
  
  <p>Can anyone help?</p>
