Unable to use InApp browser options

Hi i am a newbie to the ionic frame i am learning ionic by my self and while practising i got a problem with the InApp Browser
Below is my code
Index.html code :

<ion-header-bar class="bar-stable">

    <h1 class="title">InAppBrowser</h1>
</ion-header-bar>
<ion-content ng-controller="ExampleController" padding="true">
    <button class="button button-full button-assertive" ng-click="openInExternalBrowser()">
        Open In External Browser
    </button>
    <button class="button button-full button-assertive" ng-click="openInAppBrowser()">
        Open In App Browser
    </button>
     <button class="button button-full button-assertive" ng-click="openCordovaWebView()">
        Open In Cordova Webview
    </button>

</ion-content>

Code in App.js :

angular.module('starter', ['ionic'])

.controller("ExampleController", function ($scope) {

$scope.openInExternalBrowser = function()
{
// Open in external browser
window.open('http://192.158.0.35/new/', '_system');
};

$scope.openInAppBrowser = function()
{

// Open in app browser
window.open('http://192.158.0.35/new', '_blank', '');
};

$scope.openCordovaWebView = function()
{
// Open cordova webview if the url is in the whitelist otherwise opens in app browser
window.open('http://192.158.0.35/new', '_self', 'location=no');
};

});
