Programmatic custom element broken in dart polymer 0.9.5?

Question

The earlier solution for programmatic custom element creation in polymer 0.8.5 seems to be broken in polymer 0.9.5.

If we modify the standard click-counter example to use programmatic element creation, like so:

main() {
  Logger.root.level = Level.ALL;
  Logger.root.onRecord.listen((LogRecord rec) {   
    print('${rec.loggerName}: ${rec.level.name}: ${rec.time}: ${rec.message}');
  });

  initPolymer();

  var clickCounter = new Element.tag('click-counter');     
  document.body.children.add(clickCounter);
}

the on-click events are correctly invoking the {{increment}} method, but the {{count}} value is not updated in the HTML.

Answer 1

Polymer code should be run from

import "package:polymer/polymer.dart";

main() {
  initPolymer().run(() {
    // code here works most of the time
    Polymer.onReady.then((value) {     
      // some things must wait until onReady callback is called
      // for an example look at the discussion linked below
    });
  });
}
