Take a look at the example here: https://github.com/yapplabs/ember-modal-dialog/blob/master/README.md#controller-bound-usage

If you’re having trouble still, posting a code example of what you currently have would be a helpful way to get more precise answers.
It depends on your exact usage. But the main component could transition into a child Route.
