AngularJS w/ bootstrap dropdown does not work - angularjs

Question

I'm creating a social network site using AngularJS with bootstrap, the site is almost done but dropdown does NOT work.
I have tried many solutions online but none of them seem to work.
"ui.router" and "ui.bootstrap" are in my app.js so that is not the problem
HTML:
<div role="navigation" class="navbar navbar-default navbar-fixed-top">
<div class="container">
<div class="navbar-header">
<button data-target=".navbar-collapse" data-toggle="collapse" class="navbar-toggle collapsed" type="button">
<span class="sr-only">Toggle navigation</span>
<span class="icon-bar"></span>
<span class="icon-bar"></span>
<span class="icon-bar"></span>
</button>
{{ settings.sitename }}
</div>
<div class="navbar-collapse collapse">
<form role="search" class="navbar-form navbar-right" ng-if="isSignupPage">
<div class="form-group">
{{ 'already_registered' | translate }}
</div>
<a class="btn btn-default" ui-sref="login">{{ 'login_action' | translate }}</a>
</form>
<form role="search" class="navbar-form navbar-right" ng-if="isLoginPage">
<div class="form-group">
{{ 'no_account_signup' | translate }}
</div>
<a class="btn btn-success" ui-sref="signup">{{ 'signup_action' | translate }}</a>
</form>
</div><!--/.nav-collapse -->
</div>
</div>
I'm using angular 1.4.0

You forgot about dropdown directive. Angular bootstrap documentation says: Dropdown is a simple directive which will toggle a dropdown menu on click or programmatically.
<div class="btn-group" dropdown is-open="status.isopen">
<button id="single-button" type="button" class="btn btn-primary" dropdown-toggle ng-disabled="disabled">
Button dropdown <span class="caret"></span>
</button>
<ul class="dropdown-menu" role="menu" aria-labelledby="single-button">
<li role="menuitem">Action</li>
<li role="menuitem">Another action</li>
<li role="menuitem">Something else here</li>
<li class="divider"></li>
<li role="menuitem">Separated link</li>
</ul>
</div>
So related to your code.
<div role="navigation" class="navbar navbar-default navbar-fixed-top">
<div class="container">
<div class="navbar-header">
<button data-target=".navbar-collapse" data-toggle="collapse" class="navbar-toggle collapsed" type="button">
<span class="sr-only">Toggle navigation</span>
<span class="icon-bar"></span>
<span class="icon-bar"></span>
<span class="icon-bar"></span>
</button>
{{ settings.sitename }}
</div>
<div class="navbar-collapse collapse">
<div class="btn-group" dropdown is-open="status.isopen">
<button id="single-button" type="button" class="btn btn-primary" dropdown-toggle ng-disabled="disabled">
Button dropdown
<span class="caret"></span>
</button>
<ul class="dropdown-menu" role="menu" aria-labelledby="single-button">
<li role="menuitem">
<a href="#">
<form role="search" class="navbar-form navbar-right" ng-if="isSignupPage">
<div class="form-group">
{{ 'already_registered' | translate }}
</div>
<a class="btn btn-default" ui-sref="login">{{ 'login_action' | translate }}</a>
</form>
</a>
</li>
<li role="menuitem">
<a href="#">
<form role="search" class="navbar-form navbar-right" ng-if="isLoginPage">
<div class="form-group">
{{ 'no_account_signup' | translate }}
</div>
<a class="btn btn-success" ui-sref="signup">{{ 'signup_action' | translate }}</a>
</form>
</a>
</li>
</ul>
</div>
</div>
<!--/.nav-collapse -->
</div>
</div>
