Answer 1

It's clear that you are using click event with bootstrap component which require bootstrap javascript files. You must include it. Then you have to add a trigger to your menu. I belive the menu should be something like that :
<div class="dropdown">
<a role="button" href="#" class="dropdown-toggle"
data-toggle="dropdown" >Hello <b class="caret"></b>
</a>
<ul class="dropdown-menu" role="menu" ng-show="true">
<li>
item 1
</li>
<li>
item 2
</li>
<li>
item 3
</li>
</ul>
That is a little Plunker figure out your problem plunker.
I hope that helps
