So, ui-bootstrap-tpls.min.js == (ui-bootstrap.min.js + HTML templates) required by the JavaScript code. If you only included ui-bootstrap.min.js, you will also need to provide your own HTML templates.
Otherwise you will see something like:
GET http://localhost:8989/hello-world/template/tooltip/tooltip-popup.html 404 (Not Found) angular.js:7073
Error: [$compile:tpload] http://errors.angularjs.org/undefined/$compile/tpload?p0=template%2Ftooltip%2Ftooltip-popup.html
