dart - Dart polymer 0.9.5中损坏的程序化自定义元素？

Question

在聚合物0.8.5中用于程序化自定义元素创建的earlier solution在聚合物0.9.5中似乎已损坏。

如果我们修改standard click-counter example以使用程序化元素创建，如下所示:

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);
}

点击事件正确调用了{{increment}}方法，但是HTML中{{count}}的值未更新。

聚合物代码应从

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
    });
  });
}
