title: pusher.subcribe() is not a function
body: <pre><code> pusher.trigger('test_channel', 'my_evenHt', {"message": "hello world"});
  
     var channel = pusher.subscribe('test_channel');
    channel.bind('my-event', function(data) {
     alert('An event was triggered with message: ' + data.message);
    });
  
    pusher.trigger('test_channel', 'my_event', {"message": "hello world"});
  </code></pre>
  
  <p>I've initialized pusher at the top of the file. Here is the internals of a method thats throwing the error. The <code>pusher.trigger()</code> function works correctly, but the next line throws an error on <code>pusher.subcribe();</code></p>
  
  <blockquote>
    <p>TypeError: pusher.subscribe is not a function</p>
  </blockquote>
  
  <p>Why would this be happening?</p>
