vaadin-grid how to update table data using data binding

Is there a way to update the grid/table data using Polymer's data binding mechanism or is another mechanism required?  If another mechanism is required, I would appreciate pointer to documentation or better yet an example showing this (:  Thanks!

Also check out the

In short: binding the vaaadin-grid attribute items to a datasource will populate the grid as expected.

Thank you for the replies.

My need was to UPDATE the Vaadin grid during runtime.  After trying a few mechanism, I ended up firing a custom "update" event on the element:

this.$.vitals.fire ( "update", this.vitals );

and my custom update event listener in my element:

update : function ( event, info ) {
          this.info = info;
          this.$.table.items = this.info;
          this.$.table.size = this.info.length;
          this.$.table.refreshItems();
        }

Hope that will help someone else...
