two-way binding to paper-input doesn't work as expected

[k2s]

here is demo view https://gist.github.com/k2s/b7918cc08efc18267561

tested in application with:

• "aurelia-polymer": "github:roguePanda/aurelia-polymer@1.0.0-beta.1.0.1",
• npm:webcomponents.js@0.7.20
• bower Polymer/polymer#^1.2.0
• firstName = 'John'; is not populated to input boxes, it seams that paper-input will set empty value to the property on init (not as expected)
• editing paper-input element will update other inputs and computed property (as expected)
• editing the other input elements will update each other but not the paper-input (not as expected)

the problem was solved by moving link rel="import" to outside of template tag see updated gist
