jQuery jeditable error Object [object Object] has no method 'editable'

It looks a dummy error for this jeditable object. This is my page

<div class="edit" id="dev008">click to edit</div>

 $(function() {
     $('.edit').editable('<%= date_swimming_classschedules_path(@date)%>');
 });

And I got this error

Uncaught TypeError: Object [object Object] has no method 'editable' 

And I have checked

src="/assets/jquery.jeditable.mini.js?body=1"

It is reachable. Is there something else should I check to fix this error?

full error message in chrome console

Uncaught TypeError: Object [object Object] has no method 'editable' er:236

UPDATE.

I found this line

<script src="/assets/application.js?body=1" type="text/javascript"></script>

just after

<script src="/assets/jquery.jeditable.mini.js?body=1" type="text/javascript"></script>

is a duplicate of jQuery library. How can I remove this line?

UPDATE 2

I am adding related rails code

/app/assets/application.js code

//= require jquery
//= require jquery_ujs
//= require twitter/bootstrap
//= require underscore-min.js
//= require backbone-min.js
//= require jquery.jeditable.mini.js

/app/views/layouts/application.html.erb code

<%= javascript_include_tag "application" %>

Thanks
