How to get the ref of a custom component in parent component?

[freewind]

Say I have two custom components, one has a button, other one has a link.

When I click on the button, I want to the link of another component be clicked.

If I can get the DOM of the link from the button component, I can easily do:

linkNode.click()

But in my case, I can't find a way to get the ref of the link in the button component. If I use pure reactjs, I can do:

refs('linkComponent').refs('link').getDOMNode().click()

But how to do the same with scala-js-react?
