title: Fabric.js: How to observe object:scaling event and update properties dynamically?
body: <p>I'm trying to get the shape properties to dynamically update when the shape is being scaled.</p>
  
  <p>Here's a fiddle: <a href="http://jsfiddle.net/anirudhrantsandraves/DAjrp/" rel="nofollow">http://jsfiddle.net/anirudhrantsandraves/DAjrp/</a></p>
  
  <p>The console log commands:</p>
  
  <pre><code>console.log('Width =  '+scaledObject.currentWidth);
  console.log('Height = '+scaledObject.currentHeight);
  </code></pre>
  
  <p>are supposed to dynamically display the height and width of the shape as it is being scaled.</p>
  
  <p>The properties remain the same in the console when the shape gets scaled. However, when I select the object again and scale it, the previous values of the properties are displayed.</p>
  
  <p>Is there a way to make this dynamic?</p>
