title: Which object was modified in fabric.js
body: <p>I'm adding objects to a canvas and keeping track of their type and count number. When I add them to the canvas everything works great but when I'm modifying them I'm struggling with which object was modified in my fabric.js canvas but only if it's a cardtype.
  I want to get it's coordinates the cardtype and the cardcount. I made a <a href="http://jsfiddle.net/progrower/a4PrY/44/" rel="nofollow">fiddle</a> that shows everything working except that I get the info for all objects even when I only modify one object. How do I only get the actual activeObject and it's info?</p>
  
  <p>Here's the js in the fiddle that I've been trying to work out.</p>
  
  <pre><code>        //**********When card is moved************  
  
      canvas.on('object:modified', onObjectModified);
  
            function onObjectModified(e) {    
  
            var activeObject = e.target;
  
            alert(activeObject.get('left')+' '+ activeObject.get('top')+' '+cardtype+' '+cardcount);                  
  
         };
  </code></pre>
