Polymer: How to use custom element which is not in cuba data elements

How to I setup/use a custom element e.e https://github.com/bluewatertracks/bwt-datatable in Polymer client.

  1. Add required component to the bower.json

{
  ...
  dependencies: {
    "bwt-datatable": "bluewatertracks/bwt-datatable#^1.0.8"
  }
  ...
}
  1. Import the component

<link rel="import" href="../bower_components/bwt-datatable/bwt-datatable.html">

(please not that href path is relative)
3. Use it as any other component


<bwt-datatable ....>

It worked. Thank you.
