Unable to add cordova plugin on angularJS

I have an angularJS application. I want add ngCordova module to be enable using plugins of ngCordova ($cordovaNetwork). But I can't succeed to add ngCordova to my project. My angular project are created by Yeoman :

$ mkdir myFolderProjectAngular; cd myFolderProjectAngular
$ yo angular

Then, I add ngCordova :

$ bower install --save ngCordova
bower ngCordova#~0.1.23-alpha   cached git://github.com/driftyco/ng-cordova.git#0.1.23-alpha
bower ngCordova#~0.1.23-alpha validate 0.1.23-alpha against git://github.com/driftyco/ng-cordova.git#~0.1.23-alpha
bower ngCordova#*               cached git://github.com/driftyco/ng-cordova.git#0.1.23-alpha
bower ngCordova#*             validate 0.1.23-alpha against git://github.com/driftyco/ng-cordova.git#*
bower ngCordova#~0.1.23-alpha  install ngCordova#0.1.23-alpha

My bower.json is automatically updated :

{
  "name": "test-network",
  "version": "0.0.0",
  "dependencies": {
    "angular": "^1.4.0",
    "bootstrap": "^3.2.0",
    "angular-route": "^1.4.0",
    "ngCordova": "~0.1.23-alpha"
  },
  "devDependencies": {
    "angular-mocks": "^1.4.0"
  },
  "appPath": "app",
  "moduleName": "testNetworkApp",
  "overrides": {
    "bootstrap": {
      "main": [
        "less/bootstrap.less",
        "dist/css/bootstrap.css",
        "dist/js/bootstrap.js"
      ]
    }
  }
}

I manually add two lines on index.html :

<script src="/lib/ngCordova/dist/ng-cordova.js"></script>
<script src="/cordova.js"></script>

When I run "grunt serve" to test, my index.html is edited, the two previous line are disapear and replace by :

 <script src="bower_components/ngCordova/dist/ng-cordova.js"></script>

When I try to add cordova plugin, I have the error :

Error: Current working directory is not a Cordova-based project.

I don't understand the problem .

This is my folder project

Edit : I solved my first problem by changing folder. I create first a global folder with cordova

cordova create myApp com.organisation.myapp MyApp

On this folder I create angular project

yo angular MyApp 

After, I can add ngCordova with bower and add cordova plugin.

My problem, I can't use function of plugin. On app.js, I have :

angular.module('myAppApp', ['ngRoute', 'ngCordova' ]) ...

and on main.js, I have for example (with Toast plugin) :

 angular.module('myAppApp')
  .controller('MainCtrl', function ($scope, $cordovaToast) {
    console.log(">"); 
    $cordovaToast.show('Here is a message', 'long', 'center')
    .then(function(success) {
      // success
    }, function (error) {
      // error
    });
   console.log("<")
});

Edit : I have found my mistake. Some functionality doesn't work on browser.
