How to use Bootstrap drop down in Angular2 application?

Question

In my current project I want to add the dropdowns, for that I took the code from this link. After added the below code, the dropdown appears as in the example but when I click it nothing happens.

   <li class="dropdown">
                <a [routerLink]="['/frontendai']" class="dropdown-toggle" data-toggle="dropdown" role="button" aria-haspopup="true" aria-expanded="false">Application Insights <span class="caret"></span></a>
                <ul class="dropdown-menu" role="menu">
                    <li><a [routerLink]="['/frontendai']">FrontEnd AI</a></li>
                    <li class="divider"></li>
                    <li><a [routerLink]="['/apiai']">API AI</a></li>
                    <li class="divider"></li>
                    <li><a [routerLink]="['/apiai']">SQL Exception</a></li>
                </ul>
            </li>

I used Bootstrap version 3.3.7, and added the below lines in my index.cshtml

<link href="node_modules/bootstrap/dist/css/bootstrap.css" rel="stylesheet" />
<link href="node_modules/bootstrap/dist/css/bootstrap.min.css" rel="stylesheet" />
<script src="~/node_modules/bootstrap/dist/js/bootstrap.min.js"></script>
