Run function after hidden content has been shown

Is it possible to run a function once hidden content has been shown? For example:

$$('.hiddenContent').on('show', function (e) {
    app.dialog.alert('Ready!');
  })

Thanks.

complete: function (elements) {
            console.log('animation completed');
        },

How do you show that hidden content?

I use the following:

$$('.hiddenContent').show();

Then just call that dialog.alert right after this. It doesn’t require callback as it immediate
