Ng polymer elements Support for multiple data bindings

I have a simple age-slider web component that accepts a name and age. Something like below.

<age-slider name="{{name}}" age="{{age}}"/>

So wanted to use this with Angular. With ng polymer elements, I could only bind one variable as shown below.

<age-slider ng-model="name" age="{{age}}"/>

Can two variables be linked with ng polymer elements?
