Dropdown menu not working on heroku after deploy - ruby-on-rails

Question

I have a simple drop down menu which works great locally but when I deploy my application to Heroku, it doesn't work. It doesn't show menu options. So, when I click on Account, nothing happens.
I have added this in my production.rb file
config.assets.compile = true
config.serve_static_assets = true
config.assets.digest = true
Tired this before pushing code to Heroku, But still it not working for me
RAILS_ENV=production bundle exec rake assets:precompile
git add public/assets
git commit -m "compiled assets"
git push heroku master
Here is my code:
<% if user_signed_in? %>
<li class="dropdown">
<a class="dropdown-toggle count-info" data-toggle="dropdown" href="#" aria-expanded="false">
My Account <i class="caret"></i>
</a>
<ul class="dropdown-menu dropdown-settings">
<li>
<%= link_to user_path(current_user) do %>
<i class="fa fa-user"></i> Profile
<% end %>
</li>
<li>
<%= link_to edit_user_path(current_user) do %>
<i class="fa fa-pencil"></i> Edit Profile
<% end %>
</li>
<li>
<%= link_to edit_user_registration_path do %>
<i class="fa fa-unlock"></i> Change Password
<% end %>
</li>
<li class="divider"></li>
<li>
<%= link_to destroy_user_session_path, method: :delete do %>
<i class="fa fa-sign-out"></i> Log out
<% end %>
</li>
</ul>
</li>
<li>
<div class="m-t-sm">
<%= link_to "Logout", destroy_user_session_path, method: :delete, :class => 'fa fa-sign-out'%>
</div>
</li>
<% else %>
<li>
<div class="m-t-sm">
<%= link_to "Sign in", new_user_session_path, :class => 'btn btn-link btn-md'%> or
<%= link_to "Sign up", new_user_registration_path, :class => 'btn btn-md btn-success btn-rounded m-l'%>
</div>
</li>
<% end %>

I have solved this issue by removing this code from application.html.erb file:
<%= javascript_include_tag "application", "data-turbolinks-track" => true %>
