How to load popups without bootstrap

We are migrating our huge project from Ember 1.x to 2.3. The project has many popups which are basically regions to render views / popups. Please tell a standard way to load popups and unload them completely.

In Ember.js 1.3 we used to declared a region where popup view was loaded and we used to maintain list of popups currently loaded in the region.

Now we are switching to Ember 2.3. Please tell a specific and standard way to load popups and unload them to WITHOUT BOOTSTRAP
