angularjs template binding

I have developed a transclude directive and I set it to use angularjs template script everything works fine but I still cannot access the bind data.

My code:

index.html

<div side-element="box" title="Links">
                <ul>
                    <li>Link 1</li>
                    <li>Link 2</li>
                </ul>
</div>

<script id="box" type="text/ng-template">
            <div class="side-box">
                <div class="content">
                    <h2 class="header">Box {{ title }}</h2>
                    <span class="content" ng-transclude></span>
                </div>
            </div>
        </script>
        <script id="ad" type="text/ng-template">
            <div class="side-ad">
                <div class="content">
                    <h2 class="header">AD {{ title }}</h2>
                    <span class="content" ng-transclude></span>
                </div>
            </div>
        </script>

app.js:

angular.module('myApp.directives')
  .directive('sideElement', function ($templateCache, $log) {
return {
  scope: {
    title: '@'
  },
  transclude: 'element',
  link: function(scope, element, attrs, ctrl, transclude){
    var template = $templateCache.get(attrs.sideElement);

    var templateElement = angular.element(template);
    $log.info(scope.title);//Output the title i put in the html which is (Links)
    transclude(scope, function(clone){
      element.after(templateElement.append(clone));
    });
  }
};
});

the scope inside the link function(....) displaies the correct title but it doesn't work in the html:

Box {{ title }}

Link 1 Link 2

I think I missed one thing but I can't figure it out, I need your help to complete the cycle.

Thanx in advance,

The template element that contains the angular binding expressions must be compiled first, and then linked. The compilation phase prepares the template, while the linking phase sets up your $watchers for your binding expressions.

Demo Here

Here is a compile function that should work:

    .directive('sideElement', function ($templateCache, $compile, $log) {

    return {
      restrict: 'A',
      transclude: true,
      scope:'@',
      compile: function(element, attrs) {
        var template = $templateCache.get(attrs.sideElement);
        var templateElement = angular.element(template);
        element.append(templateElement);
        return function(scope, element, attr, ctrl, transclude) {
          $log.info(scope.title);
        }
      }
    }
