¿How to use routes inside a Modal in Emberjs?

sorry for my English. I will try to explain better I can.

I have an application in EmberJS, this application have its routes. Also, when I click in a button, I should show a Modal Window and change the route. That problem was resolved. The problem is. This modal window must to be a kindly of wizard, so when the user click on next, I should to change the route and show inside the modal the correct content, when the user click in next again, the route must to change again but the new content should be showed into the modal too.

The problem seems to be, ember takes my application outlet and show the new content inside that outlet, not inside of the outlet defined into the modal.

How I achieve this?
