title: skype uri button in angularjs issue
body: <p>I'm trying to add skype button to my project using AngularJS. Here's the code:</p>
  
  <p>HTML:</p>
  
  <pre><code>&lt;script type="text/javascript" src="http://www.skypeassets.com/i/scom/js/skype-uri.js"&gt;&lt;/script&gt;
  
  &lt;skype-ui id="SkypeButton_Call_1" participants="participants"&gt;
                  &lt;/skype-ui&gt;
  </code></pre>
  
  <p>AngularJs:</p>
  
  <pre><code>app.directive("skypeUi", function () {
      return {
          restrict: "E",
          template: "&lt;div&gt;&lt;/div&gt;",
          replace: true,
          scope: {
              participants: "="
          },
          link: function (scope, element, attrs) {
              Skype.ui({
                  "name": "chat",
                  "element": attrs.id,
                  "participants": scope.participants,
                  "imageSize": 32
              });
          }
      };
  });
  </code></pre>
