My views/comments/create.js.erb JS is not working and my erb does give some output, I setup my jQuery by adding

gem 'jquery-rails', '~> 4.4'

I bundles my rails app and made changes in the app/asset/javascript/application.js with the requires as follows

//= require jquery
//= require jquery_ujs
//= require turbolinks
//= require_tree .
//= require activestorage

So when i write my js for create action of comment in app/views/comments/create.js.erb

$('#comment_content').val('')
$('#comment_div').prepend(<%= j render @comment %>)

And i have a partial with _comment.html.erb

<%= comment.created_at.strftime("%l:%M:%p")%>
<b><%= comment.user.username %></b>
<%= comment.content %>
<br>

Now i dont know where i have made mistake in setting up my jquery
