Answer 1

If your execute() method in the controller outputs whatever code directly, there is no layout rendered and also there are no javascript libraries loaded.

It's better to create a to create a layout xml file for your controller and a phtml template and include the javascript code there. That will work unless you remove in your layout xml the blocks which are loading the javascript libraries.
