Loading an AngularJS directive after an already fully loaded controller

I've got an AngularJS project in which I want to load a directive from a package X just after a controller from package Y will be fully loaded.

My main problem is that the controller is retrieving some data from a db and the directive needs that data to work as expected. Right now, the directive is finishing its loading before the data is fully loaded, so it doesn't work properly.

I need to get the directive starts to work when the controller (and what's more important, the data!) will be fully loaded.

Any suggestion?

Thanks in advance!
