angular smart table not working

I am using smart table http://lorenzofox3.github.io/smart-table-website/ and I am trying to follow pipe/ajax plugin example. But its not showing any data. this is what I have in my html

<div ng-controller="AboutCtrl">
  <table class="table" st-pipe="mc.callServer" st-table="mc.displayed">
    <thead>
    <tr>
      <th st-sort="id">id</th>
      <th st-sort="name">name</th>
      <th st-sort="age">age</th>
      <th st-sort="saved">saved people</th>
    </tr>
    <tr>
      <th><input st-search="id"/></th>
      <th><input st-search="name"/></th>
      <th><input st-search="age"/></th>
      <th><input st-search="saved"/></th>
    </tr>
    </thead>
    <tbody ng-show="!mc.isLoading">
    <tr ng-repeat="row in mc.displayed">
      <td>{{row.id}}</td>
      <td>{{row.name}}</td>
      <td>{{row.age}}</td>
      <td>{{row.saved}}</td>
    </tr>
    </tbody>
    <tbody ng-show="mc.isLoading">
    <tr>
      <td colspan="4" class="text-center">Loading ... </td>
    </tr>
    </tbody>
    <tfoot>
    <tr>
      <td class="text-center" st-pagination="" st-items-by-page="10" colspan="4">
      </td>
    </tr>
    </tfoot>
  </table>

</div>

and here is my js

angular.module('eventsApp')
  .controller('AboutCtrl', ['Resource', function (service) {

    var ctrl = this;

    this.displayed = [];

    this.callServer = function callServer(tableState) {

      ctrl.isLoading = true;

      var pagination = tableState.pagination;

      var start = pagination.start || 0;     // This is NOT the page number, but the index of item in the list that you want to use to display the table.
      var number = pagination.number || 10;  // Number of entries showed per page.

      service.getPage(start, number, tableState).then(function (result) {
        ctrl.displayed = result.data;
        tableState.pagination.numberOfPages = result.numberOfPages;//set the number of pages so the pagination can update
        ctrl.isLoading = false;
      });
    };

  }]).factory('Resource', ['$q', '$filter', '$timeout', function ($q, $filter, $timeout) {

  //this would be the service to call your server, a standard bridge between your model an $http

  // the database (normally on your server)
  var randomsItems = [];

  function createRandomItem(id) {
    var heroes = ['Batman', 'Superman', 'Robin', 'Thor', 'Hulk', 'Niki Larson', 'Stark', 'Bob Leponge'];
    return {
      id: id,
      name: heroes[Math.floor(Math.random() * 7)],
      age: Math.floor(Math.random() * 1000),
      saved: Math.floor(Math.random() * 10000)
    };

  }

  for (var i = 0; i < 1000; i++) {
    randomsItems.push(createRandomItem(i));
  }


  //fake call to the server, normally this service would serialize table state to send it to the server (with query parameters for example) and parse the response
  //in our case, it actually performs the logic which would happened in the server
  function getPage(start, number, params) {

    var deferred = $q.defer();

    var filtered = params.search.predicateObject ? $filter('filter')(randomsItems, params.search.predicateObject) : randomsItems;

    if (params.sort.predicate) {
      filtered = $filter('orderBy')(filtered, params.sort.predicate, params.sort.reverse);
    }

    var result = filtered.slice(start, start + number);

    $timeout(function () {
      //note, the server passes the information about the data set size
      deferred.resolve({
        data: result,
        numberOfPages: Math.ceil(filtered.length / number)
      });
    }, 1500);


    return deferred.promise;
  }

  return {
    getPage: getPage
  };

}]);

and this is what my browser show

Try change this

<div ng-controller="AboutCtrl">

to

<div ng-controller="AboutCtrl as mc">
