The problem is, that file uses a class from a different namespace, so when I try to run php migrations.php, I get Fatal error: Uncaught Error: Class "Core\Database\Database" not found in C:\Users\user\Desktop\app\migrations.php:6.

I am using composer's autoloader and I have no issues with other files - this only happens when I try to execute the mentioned file from command line.

My problem now is that I want to have a dynamic onClick function which is created inside a javascript class. But the onClick event is not fired.

I use webpack for my javascript

When I've everything in the app.js it was working. Now I want to make my app more OOP like, so I realized my classes and import them.

The problem is that the event onClick is not fired. I tried it with an id but also not working. Also a problem is the this-context.

I think the problem has something to do with the route. For some onChange functionality I've to put the code into pageInit inside the app.js then it was working.

I tried the same with onClick in default view. Cause I need this event on the defaul site/view.
