title: Twitch TV API accessing property name value and updating it
body: <p>I have created a list of Twitch TV thumbnails using JSON. I would like to create an option where I can click on thumbnail and popup tab with that video to appear. For that, I need to access to API code "options" property and change "channel" value.
  I have tried to access that property and change value in function popup() which is triggered by clicking on thumbnail ; </p>
  
  <pre><code>&lt;div id="popup"&gt;
  &lt;div id="videoWrapper"&gt;
  
  &lt;script src= "http://player.twitch.tv/js/embed/v1.js"&gt;&lt;/script&gt;
  &lt;div id="test"&gt;&lt;/div&gt;
  &lt;script type="text/javascript"&gt;
      var options = {
          width: 600,
          height: 315,
          channel: "monstercat", 
          //video: "v123456789"   
      };
      var player = new Twitch.Player("test", options);
      player.setVolume(0.01);
      //player.setMuted(true);
  
  
  
          //Popup Tab with streaming video
              function popup(){
                  $('#popup').show();
                  options.channel = 'nl_kripp';   
              }
  
  
  &lt;/script&gt;
  </code></pre>
  
  <p>Do You maybe know what I am doing wrong here becasue this is not working?</p>
