Errors using the ngCordova $cordovaSQLite plugin with Ionic

I am currently trying to implement the ngCordova SQLite plugin with my app but have yet to produce a working solution. I have followed Nic Raboy's blog post on how to implement the SQLite plugin with your Ionic project to a "T," but I am still receiving the error: Error: undefined is not an object (evaluating '$window.sqlitePlugin.openDatabase') when I try to run the application in the iOS emulator.

I have also verified that ngCordova and the plugin have been loaded into my project.

This is the order of how my scripts are getting loaded into my project:

<script src="lib/ionic/js/ionic.bundle.js"></script>
<script src="lib/ngCordova/dist/ng-cordova.js"></script>
<script src="cordova.js"></script>
<script src="js/app.js"></script>
<script src="js/controllers.js"></script>

My code is below.

app.js

angular.module('whoPaidLast', ['ionic', 'ngCordova', 'whoPaidLast.controllers', 'whoPaidLast.services'])

.run(function($ionicPlatform, $cordovaSQLite) {
    $ionicPlatform.ready(function() {
        if(window.cordova && window.cordova.plugins.Keyboard) {
            cordova.plugins.Keyboard.hideKeyboardAccessoryBar(true);
        }
        if(window.StatusBar) {
            StatusBar.styleDefault();
        }

        db = $cordovaSQLite.openDB({ name: 'accounts.db' });
        $cordovaSQLite.execute(db, 'CREATE TABLE IF NOT EXISTS accounts (id integer primary key autoincrement, firstname text, lastname text, paid numeric, date text)');
    });
})

controllers.js

angular.module('whoPaidLast.controllers', [])

.controller('DashCtrl', ['$ionicPlatform', '$scope', '$ionicModal', '$ionicActionSheet', '$cordovaSQLite', function ($ionicPlatform, $scope, $ionicModal, $ionicActionSheet, $cordovaSQLite) {

    $scope.getList = function() {
        var query = 'SELECT id, firstname, lastname, paid, date FROM accounts ORDER BY lastname ASC';
        var db = $cordovaSQLite.openDB({ name: 'accounts.db' });

        $ionicPlatform.ready(function() {
            $cordovaSQLite.execute(db, query, [id, firstname, lastname, paid, date]).then(function(result) {
                if(result.rows.length > 0) {
                    console.log('rows =' + result.rows);
                } else {
                    $scope.results = [];
                }
            }, function(error) {
                console.error(err);
            });
        });
    };
});

Any information or help that you may have would help. Thanks ahead of time.
