[phd-table]: Cannot pass specific properties on cell click

[jmzagorski]

e.g.

renderer: (): string =>
  `<a href="javascript:void(0)"
        click.delegate="_setFilter(row.item.item.displayName)"
    >\${row.item.item.displayName}</a>`

does not pass the nested item.displayName property. It always passes the row. Ideally we should use cell-click.call=externalFunction(args), might be better than just passing the row arg on click.

The binding in general is not setup great or wrorking as easy as I hope...e.g a click target may be the inner text of the button and ot the element with click.delegate
