angular-pull-to-refresh | CSS3 Pull-to-Refresh directive for AngularJS | Frontend Framework library

I'm a complete beginner and I don't have any idea, how include libraries and inject module, so please, bear with me. This is the module I want to include: https://github.com/mgcrea/angular-pull-to-refresh

I installed module with bower and successfully linked them. and should be in app.component.html right? Or should I link it in component named list (list.component.html) where I show data, which I want to refresh with pulldown?

Could you point me in the right direction, where to put this line and what exactly does 'myApp' represent here.
- Inject the mgcrea.pullToRefresh module into your app:
angular.module('myApp', ['mgcrea.pullToRefresh']);

And at the example, pull-to-refresh attribute is called and within function onReload(). Where should this function be located?

Thank you all for reading and helping me!
