Controller loaded by ng-include not working - angularjs

Question

I have a page with a pop-up I use on several pages and I load it using ng-include. In this pop-up there is three tabs also dynamically loaded using ng-include.
So my code looks like this:
<div ng-include="'/pages/ng-templates/Cockpit.html'"></div>
in Cockpit.html I have the following code:
<div id="dlgCockpit" class="Cockpit jquerydialog">
<div id="tabs">
<ul>
<li>tabA</li>
<li>tabB</li>
<li>tabC</li>
</ul>
<div id="tabA">
<div ng-include="'/pages/ng-templates/Cockpit-A.html'"></div>
</div>
<div id="tabB">
<div ng-include="'/pages/ng-templates/Cockpit-B.html'"></div>
</div>
<div id="tabC">
<div ng-include="'/pages/ng-templates/Cockpit-C.html'"></div>
</div>
</div>
</div>
<script src="/pages/ng-templates/scripts/Cockpit.js"></script>
In Cockpit-A.html I have the following Code:
<div id="dlgCockpitA">
<form name="frmA" class="cntrCockpitA form" ng-controller="AController">
<!-- some inputs using ng-model -->
</form>
</div>
<script src="/pages/ng-templates/scripts/Cockpit-A.js"></script>
Cockpit.js:
function showCockpit(vsTnID, vsBenutzer) {
$('#dlgCockpit').data('tnid', vsTnID);
var $dialog = $("#dlgCockpit")
.dialog({
autoOpen: false,
title: locBenutzer + ': ' + vsBenutzer + ' (ID: ' + vsTnID + ')',
width: 1000,
show: 'fade',
resizable: false,
open: function (event, ui) {
$("#tabs").tabs({ active: 0 });
angular.element($('.cntrCockpitA')).scope().showStammdaten(vsTnID, 'Standard');
},
close: function (event, ui) {
}
});
$dialog.dialog('open');
return false;
}
Cockpit-A.js:
app.controller('AController', ['$scope', '$http', function ($scope, $http) {
//some function definitions on $scope
}]);
When I load the page I get the following in the javascript console:
Error: [ng:areq] Argument 'AController' is not a function, got undefined

at publicLinkFn (http://localhost:63323/scripts/angular/angular-1.2.26.js:6001:30)
When calling showCockpit I get the following error in the line angular.element($('.cntrCockpitA')).scope().showStammdaten(vsTnID, 'Standard');:
Uncaught TypeError: undefined is not a function
Actually everything works if I put the script tag for Cockpit-A.js in the "base page" which is including Cockpit.html or if I create the Controller just by calling function AController($scope, $http) { ... }, but both of those are not an option.

Answer 1

I had the exact same problem. Found a solution thanks to: http://ify.io/lazy-loading-in-angularjs/
Basically, it is not possible to use app.controller(...) after bootstrapping the app. I suggest reading the link for more information. The solution is to save the controllerProvider ahead and use it to register the module.
var app = angular.module('myModule', []);
app.config(function($controllerProvider) {
app.controllerProvider = $controllerProvider;
});
// Later on... after bootstrapping...
app.controllerProvider.register('myController', function() {... });
