Rails - Mar 2012 - The problem with Ajax based micropost's comments

I have ajax based micropost''s comments on the user page. It works, but
not correctly. When I submit a new comment to ANY micropost, it always
posts to the LAST micropost! Then, if I refresh the page by "F5",
everything falls into place - the new comment is in the correct
micropost. What I''m doing wrong? Thanks in advance.

comment.rb

class Comment < ActiveRecord::Base
  attr_accessible :comment_content
  belongs_to :user
  belongs_to :micropost
end


comments_controller.rb

class CommentsController < ApplicationController
  before_filter :signed_in_user, only: [:create, :destroy]

   def create
    @micropost = Micropost.find(params[:micropost_id])
    @comment = Comment.new(params[:comment])
    @comment.micropost = @micropost
    @comment.user = current_user
      respond_to do |format|
      @comment.save
           format.html { redirect_to current_user }
           format.js
      end
   end
end


_micropost.html.erb

<tr>
  <td class="micropost">
    <span class="content"><%= wrap(micropost.content)
%></span>
    <span class="timestamp">
    Posted <%= time_ago_in_words(micropost.created_at) %> ago.
    </span>
    <%= render ''shared/comment_form'', micropost: micropost
%>
   <div id="comments">
     <%= render micropost.comments %>
   </div>
  </td>
</tr>


_comment_form.html.erb

<%= form_for ([micropost, @comment]), :remote => true do |f| %>
<%= render ''shared/error_messages'', object: f.object %>
<%= f.text_area :comment_content, :size => "40x2" %>
  <button class="btn" type="submit">
    Comment
  </button>
<% end %>


_comment.html.erb

<span style="width: 100%;
background:#dff0d8"><%wrap(comment.comment_content)
%></span>
<span class="timestamp">
 Posted by <%= comment.user.name %>
<%time_ago_in_words(comment.created_at) %> ago.
</span>


create.js.erb

$(''#comments'').html("<%=
escape_javascript(render(:partial =>
@micropost.comments)) %>");

First look in development.log and check that the correct parameters
are being passed in.  Then have a look at the Rails Guide on Debugging
which will show you a number of techniques that can be used to debug
the code.
