Scope Not Updating When Using ng-click Within a Component

I have the issue that my scope is not updating when using ng-click within a component. The scope also does not update if I use $scope.$apply or $timeout so I am not sure what the issue is.

The idea is that when I click on my second button within my component (qdcPopover.html) that $scope.showGetData should be updated to true which will then update the div within my index.html.

Here is my code:

index.html:

<html lang="en" qva-bootstrap="false">
<head>
  <title>Data Prep</title>
  <script data-main="data-prep" src="/resources/assets/external/requirejs/require.js"></script>
</head>
<body>
  <div ng-controller="AppCtrl as ctrl">
    <button id="qdpCreateApp" class="lui-button  lui-button--rounded">Create App</button>
    <qdp-popover></qdp-popover>
    <div>Hello {{showGetData}} + {{showAppCreate}}</div>
  </div>
</body>
</html>

qdpPopver.html (component)

<div ng-show="showAppCreate" class="lui-popover" style="width: 400px;">
  <div class="lui-popover__header">
    <div class="lui-popover__title">{{qdpPopover.title}}</div>
  </div>
  <div class="lui-popover__body">
    {{qdpPopover.body}}
    <input id="{{qdpPopover.inputId}}" ng-show="qdpPopover.showInput" class="lui-input"/>
  </div>
  <div class="lui-popover__footer">
    <button class="lui-button  lui-popover__button" ng-click="showAppCreate = false">{{qdpPopover.button1}}</button>
    <button class="lui-button  lui-popover__button" ng-click="createApp()">{{qdpPopover.button2}}</button>
  </div>
</div>

data-prep-module.js

// define the angular module with its controller
var app = angular.module('qlikDataPrepModule', []);

// define angular components
app.component('qdpPopover', {
    templateUrl: 'qdpPopover.html',
    controller: 'AppCtrl'
})

var qdpAppNameInput = "qdpAppNameInput";
// Controller
app.controller('AppCtrl', function ($scope, $location, $http, $timeout) {
    $scope.qdpPopover = {
        title: "Create new App",
        body: "Name of my app:",
        button1: "Cancel",
        button2: "Create",
        showInput: true,
        inputId: qdpAppNameInput
    };
    $scope.showGetData = false;
    $scope.showAppCreate = false;

    // Function for app creation
    $scope.createApp = function () {
        $scope.showGetData = true;
        $scope.$apply();
    }
})
