Set loading state when promise is set after click

[ghost]

Loading state wasn't initialized if handleCurrentBtnOnly is true, and promise is added after click.

I replaced addEventListener with HostListener as the angular guide suggests.

It also fixes a memory leak, as the event listener wasn't detached when directive is destroyed.

Of course you could reach into the DOM with standard JavaScript and and attach event listeners manually. There are at least three problems with that approach:

You have to write the listeners correctly.
The code must detach the listener when the directive is destroyed to avoid memory leaks.
Talking to DOM API directly isn't a best practice.

@johannesjo could you please release a new version with all my changes? I use your module in several projects and I'd like to use the latest code :-)

My pleasure. If you have any kind of todo list of things you'd like to improve in your module, please share. Maybe I can help you with something.
