title: Spine.js - How do you unbind a specific event handler from a model instance using JavaScript?
body: <p>It's pretty easy to unbind specific event handlers from model classes, but it seems the only way to unbind an event handler from an instance of a model is to unbind ALL event handlers attached to that instance using <code>unbind()</code> (takes no arguments).</p>
  
  <p>Is there an equivalent to Model class' <code>unbind([eventName, function])</code> function for model instances, or is there another better way to unbind specific handlers without unbinding them all?</p>
  
  <p>I've looked through the <a href="http://spinejs.com/api/models" rel="noreferrer">Spine.js documentation</a> but no luck so far. Adding arguments to the <code>unbind()</code> function has no effect - it just ignores them and unbinds all anyway.</p>
