title: Call function when "on scroll" event is triggered
body: <p>I have a grid that is locally initialized from an array data. after adding the rows to it I want to be able to get the event of the scrollbar when it reaches to the end and load more rows locally.
  (the grid has certain height and <code>'overflow-y' : scroll</code>)</p>
  
  <p>How can this be done?</p>
  
  <p>Thanks In Advance.</p>
