title: What is the difference between sendAction and send?
body: <p>I have defined two custom objects, whereby the first one is extending Ember.TextField and the second one Ember.Select. When the appropriate action is trigger in Ember.TextField I do some processing and if a requirement is satisfied then I propagate the action to the underlying controller using <code>@sendAction("actionName")</code>.</p>
  
  <p>However, when I try to do the same using Ember.Select I get the following Error: </p>
  
  <pre><code>Uncaught TypeError: Object [object Object] has no method 'sendAction' 
  </code></pre>
  
  <p>and have to use <code>@get("controller").send("actionName")</code> instead. My mentor reckons that this inconsistency leads to spaghetti code and I do agree with him. Why can't I call <code>@sendAction</code> from Ember.Select, which is a preferred way I've come to understand, in Ember?</p>
  
  <p>What is the main difference between the two?</p>
