I know that I have been able to insert polymer elements into the DOM pretty easily, but I declared all the element types at start time. As a matter of fact, I kind of thought that all the link rel imports had to be in the document head. I'd try that part first, to see if it's the item declaration that's the problem or the injectoin.

Importing "paper-button" in a <head> of index.html doesn't help.
BTW, a live demo of my example can be found here http://dzhioev.net:8000/

This doesn't work because you're taking elements from an xhr document where there's no custom element registry and then just moving them. You need to do appendChild(document.importNode(response.body.children[0])) which will create a clone of the node, but using the document where polymer has registered the custom elements.

Ah yeah, that makes sense. I only ever dynamically add polymer elements by doing a document.createElement and then appendChild it.
