template - string | function | jQuery object

Specify your content for popin here, it can be string value:

Also it accepts jQuery objects (dynamic as well), so you can create element with content inside your app:

<div class="content" style="display: none;">
    My content for popin!

and use it in template of popin:

    template: $('.content')
