html - Bootstrap 3 collapse button appears but no effect when clicked?

I'm trying to make it so that when I click my collapse button, the two labels will appear, but it's not happening even though the data-target and id (colnav) of the navbar are same. 

<nav class="navbar navbar-inverse navbar-fixed-top">
      <div class="container">
        <div class="navbar-header">
          <button type="button" class="navbar-toggle" data-toggle="collapse" data-target="#colnav">
            <span class="icon-bar"></span>
            <span class="icon-bar"></span>
            <span class="icon-bar"></span>                        
          </button>

          <a class="navbar-brand" href="#">
            <%= image_tag("iinfo.png", :alt => "INFOMAN") %>
          </a>
        </div>

      <div class="collapse navbar-collapse" id="colnav">

            <ul class="nav navbar-nav navbar-right" >
              <li class="color-me">
                <a href="#" style="color:red">
                  Contact Us
                </a>
              </li>
              <li>
                <% if current_user %>
                <%= link_to 'Logout', session_path("new") , method: "delete"%>
                <% end %>
              </li>
            </ul> 
      </div><!--/.navbar-collapse -->

    </div>
</nav>

Bootstrap requires jQuery for its effects. If you're requiring bootstrap via its CDN, you need to ensure that jquery is loaded in your application.html.erb. See this official template. 

<!DOCTYPE html>
<html lang="en">
  <head>
    <!-- Bootstrap -->
    <link href="css/bootstrap.min.css" rel="stylesheet">
  </head>
  <body>
    <h1>Hello, world!</h1>

    <!-- jQuery (necessary for Bootstrap's JavaScript plugins) -->
    <script src="https://ajax.googleapis.com/ajax/libs/jquery/1.12.4/jquery.min.js"></script>
    <!-- Include all compiled plugins (below), or include individual files as needed -->
    <script src="js/bootstrap.min.js"></script>
  </body>
</html>

However, if you're requiring bootstrap through the bootstrap gem, then you need to ensure that gem 'jquery-rails' is in your gemfile, and your application.js manifest file requires jquery.

See the gem documentation for correct installation details.

Hope this helps!

This issue usually happens when you haven't linked your bootstrap.min.js file correctly.
