AngularJS and Ionic Framework: module is not available error

When loading my webpage, I get the following errors:

Error: [ng:areq] Argument 'LFSTD' is not a function, got undefined

Uncaught ReferenceError: controller is not defined

The webpage i'm loading has the ng-app attribute in the body tag, and a Ionic tag has the ng-controller:

<body ng-app="ia">
[...]
<ion-side-menu-content ng-controller="LFSTD">

"ia" and "LFSTD" are both defined in app.js. The webpage does load the following static files correctly

network

This is app.js:

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

.run(function ($ionicPlatform) {
$ionicPlatform.ready(function () {
    controller('LFSTD', function($scope, $ionicSideMenuDelegate) {
        $scope.toggleLeft = function() {
            $ionicSideMenuDelegate.toggleLeft();
        };
    });
});
})

I've been struggling with this, lurking stackoverflow and ionic/angular docs for quite a while. It might be worth saying that my project uses Django. Any idea what might be causing these errors?

Solution

angular
.module('ia', ['ionic'])
.config(function ($routeProvider) {
$routeProvider
    .when('/', {
        templateUrl: 'create.html',
        controller: 'LFSTD'
     })
 }
.run(function ($ionicPlatform) {
$ionicPlatform.ready(function () {
    controller('LFSTD', function($scope, $ionicSideMenuDelegate) {
        $scope.toggleLeft = function() {
            $ionicSideMenuDelegate.toggleLeft();
        };
    });
});
})

I was missing the .controller part in app.js. I thought I could include controllers in a function, but no. It needs to be directly after the angular.module. See updated question.
