How to auto refresh Ionic List

Question

I am trying to auto refresh a list displayed using Ionic 1. I have found this pen but not able to understand how it works.

https://codepen.io/calendee/pen/GkgsD?editors=1111

The code below gives the list which I am trying to refresh

<ion-content ng-controller="myController" ng-init="init()">
          <div class="list">
             <a ng-repeat="entry in entries" class="item" ng-click="browse(entry.link)">
               <b>{{entry.title}}</b><br>
               <span ng-bind-html="entry.contentSnippet"></span>

             </a>

          </div>
      </ion-content>

$http.get("http://ajax.googleapis.com/ajax/services/feed/load", { params: { "v": "1.0", "q": "https://community.woltlab.com/board-feed/?l=2", "num": "100" } })

app.js

var rssApp = angular.module('myApp1', ['ionic'])

.run(function($ionicPlatform) {
  $ionicPlatform.ready(function() {
    if(window.cordova && window.cordova.plugins.Keyboard) {
      // Hide the accessory bar by default (remove this to show the accessory bar above the keyboard
      // for form inputs)
      cordova.plugins.Keyboard.hideKeyboardAccessoryBar(true);

      // Don't remove this line unless you know what you are doing. It stops the viewport
      // from snapping when text inputs are focused. Ionic handles this internally for
      // a much nicer keyboard experience.
      cordova.plugins.Keyboard.disableScroll(true);
    }
    if(window.StatusBar) {
      StatusBar.styleDefault();
    }
  });
})

rssApp.controller("myController", function($http, $scope) {

    $scope.init = function() {
        $http.get("http://ajax.googleapis.com/ajax/services/feed/load", { params: { "v": "1.0", "q": "https://community.woltlab.com/board-feed/?l=2", "num": "100" } })
            .success(function(data) {
                $scope.rssTitle = data.responseData.feed.title;
                $scope.rssUrl = data.responseData.feed.feedUrl;
                $scope.rssSiteUrl = data.responseData.feed.link;
                $scope.entries = data.responseData.feed.entries;
                window.localStorage["entries"] = JSON.stringify(data.responseData.feed.entries);
            })
            .error(function(data) {
                console.log("ERROR: " + data);
                if(window.localStorage["entries"] !== undefined) {
                    $scope.entries = JSON.parse(window.localStorage["entries"]);
                }
            });
    }

        $scope.browse = function(v) {
        window.open(v, "_blank", "location=no");
    } 
});

 $scope.init = function() {

    $http.get("https://ajax.googleapis.com/ajax/services/feed/load", {
        params: {
          "v": "1.0",
          "q": "https://community.woltlab.com/board-feed/?l=2",
          "num": "100"
        }
      })
      .success(function(data) {
     
       $scope.data = data;
        $scope.rssTitle = data.responseData.feed.title;
        $scope.rssUrl = data.responseData.feed.feedUrl;
        $scope.rssSiteUrl = data.responseData.feed.link;
        $scope.entries = data.responseData.feed.entries;
        window.localStorage["entries"] = JSON.stringify(data.responseData.feed.entries);
      })
      .error(function(data) {
        
         $scope.data = data;
        console.log("ERROR: " + data);
        if (window.localStorage["entries"] !== undefined) {
          $scope.entries = JSON.parse(window.localStorage["entries"]);
        }
      });
  }

  $scope.browse = function(v) {
    window.open(v, "_blank", "location=no");
  }
  $interval(function() {
   $scope.init();
  }, 5000);
});

You need to refresh the data after some interval .Angular have $interval service which will callback function after specified time.here is plunker https://plnkr.co/edit/KB9das?p=info

$interval(function() {
reloadNumber++;
console.log('refreshed nth times ', reloadNumber)
$scope.getPosts();

}, 5000);

var app = angular.module('plunker', []);

app.controller('MainCtrl', function($scope, $http, $interval) {
  $scope.name = 'World';


  var root = 'https://jsonplaceholder.typicode.com';
  var reloadNumber = 0;
  $scope.getPosts = function() {
    $http({
      url: root + '/posts',
      method: 'GET'
    }).then(function(data) {
      $scope.posts = data.data;
      console.log(data);
    });
  }
  $scope.getPosts();
  $interval(function() {
    reloadNumber++;
    console.log('refreshed nth times ', reloadNumber)
    $scope.getPosts();

  }, 5000);

});
