Carto.js Infowindow Listeners open/close Events

Question

I have a website with the carto.js library and some layers loaded. If I click on a feature, an Infowindow is opening up.

I know that there is an event for the feature click:

sublayer.on('featureClick', function(e, latlng, pos, data) {
          alert("Hey! You clicked " + data.cartodb_id);
    });
  }).on('error', function() {
        //log the error
});

But I have not found any information on how to listen for the close event. Is it possible to create a listener on the close event of the infowindow?

Usecase: Change map content while the popup is open.

Check this example, it's using a custom infowindow but has the important bits you need. It's all about accessing the backbone model and then subscribing to the visibility change.
