I wish this helpful for you I create a paper button dynamically (and add it to the dom tree). Looks fine, but I need to add an action to it by catching an "on pressed" event: , You can create the callback like this:
code :
void onButtonClicked(Event event, var detail, Element target) {
  // do something
}
NewPaperButton.onClick.listen(onButtonClicked);

it should still fix some issue In Angular you usually pass $event to have the event object available in the handler
code :
@Component(
    selector: 'my-cmp',
    publishAs: 'cmp',
    template: r'<div><paper-button ng-click="cmp.clickHandler($event)" label="click me"></paper-button></div>'
)
class MyComponent {
  void clickHandler(dom.Event event) {
    print('clicked: $event');
  }
}

like below fixes the issue If you use a paper-button you should use paper-button as selector. Why do you think button is a valid selector for a paper-button?

code :
import 'dart:html';
