By default Polymer 1.0 does not use the full Shadow DOM polyfill, so most
DOM operations need to go through a special "Shady DOM" API so that Polymer
knows to re-compute the composed DOM when the document changes. These APIs
are available by calling Polymer.dom() on the element you wish to modify,
in your example:
Polymer.dom(g).appendChild(document.createElement('paper-radio-button'))
See these docs for more:
https://www.polymer-project.org/1.0/docs/devguide/local-dom.html#dom-api
Hope that helps!
