Ember Nested Routes Break Named Outlet

I have a Parent route named engineering. Every route extends a Base.js route which renders the default template as well as another custom one into the named outlet:

renderTemplate: function (controller) {
    this.render();

    this.render('page-title', {
        outlet: 'pageTitle',
        controller: controller,
    });
},

There is a engineering.hbs parent template which contained two outlets. The Main and another {outlet 'pageTitle'}}.

This works perfecly fine for routes like /engineering/index and engineering/someothersite, but the pageTitle outlett just doesn't render at all for routes like engineering/college/courses/description.

Any Suggestions, or perhaps even a better way of passing data from a child route to the parent template?
