How to dynamically call edit action and render partial - Rails 4

I am making a blog system and I want to add some AJAX magic into it.

I have an edit and delete action in the view:

<% @post.comments.each do |comment| %>
  <div class="row comment">
    <div class="row comment-creator">
      <div class="col-sm-1 text-center">
        <%= image_tag comment.user.profile.avatar.url(:thumb), class:"thumbnail" %>
      </div>
      <div class="col-sm-11">
        <div class="row">
          <div class="col-sm-9">
            <p class="fullname"><%= current_user.profile.first_name %> <%= current_user.profile.last_name %></p>
            <span class="datetime"> <%= l comment.created_at, format: :datetime %> </span>
          </div>
          <div class="col-sm-3 post-actions text-right">
            <% if current_user == comment.user %>
              <%= link_to "Edit comment", edit_blog_comment_path(comment) %> |
              <%= link_to "Delete", blog_comment_path(comment), method: :delete, data: { confirm: "You sure?" } %>
            <% end %>
          </div>
        </div>

        <div class="well row comments-well">
          <div class="col-sm-10">
            <%= comment.body %>
          </div>
          <% if comment.attachment? %>
            <div class="col-sm-2 text-center">
              <%= image_tag comment.attachment.url(:thumb) %>
              <span>attachment</span>
            </div>
          <% end %>
        </div>

      </div>

    </div>

<% end %>

Instead of clicking the edit button and redirecting to the edit action, I want to render the edit form dynamically for a given comment and later on submit the changes via AJAX.

How can I do that?
