    app.controller('LoginCtrl', ['$scope', function($scope) {
        $scope.login = function () {

If you use a newer version of Ionic it works: http://plnkr.co/edit/K2BLrUyOEeoDxHc9LyTl?p=preview

I used http://code.ionicframework.com/1.0.0/js/ionic.bundle.min.js

your example uses http://code.ionicframework.com/1.0.0-beta.1/js/ionic.bundle.min.js

requirejs.config({
paths: {
    ionic:'http://code.ionicframework.com/1.0.0/js/ionic.bundle.min',
},
shim: {
    ionic : {exports : 'ionic'}
}, priority: [
    'ionic'
],

deps: [
    'bootstrap'
]

});
