Make View->on(event, [jsAction1, jsAction2]) work
Make View->on(event, [jsAction1, jsAction2]) work

If an array containing only JS actions was used as second parameter of View->on, it failed and threw the error message:
atk4\ui\Exception: You cannot add anything into the view after it was rendered

Now JS actions are merged into $actions array and it works as intended.
