Angular2 paper-input variable value

In Angular2 u can assign a value to a variable like this:

<input #newName="ngForm" ngControl="newName"> 

How do i do the same thing after i changed the form to ?

<paper-input #newName="ngForm" ngControl="newName" label="NewName"> </paper-input> I tried this, but it gives me an error:

No value accessor for 'newName'

Hi there!

Are you using the PolymerElement(‘paper-input’) directive from ‘angular2-polymer’ library?
