Error when using x-editable with BS3 - cakephp

Question

I want to make a simple use of the plugin x-editable, following step by step what's to do in the official doc.
It actualy worked fine when I was on Bootstrap 2, though, it doesn't work anymore on BS3 (even if I updated everything to the latest version etc.).
So when I click on the link to trigger the editable popover, I got this error in firebug :
TypeError: this.$element.data(...) is undefined
[...]/Bootstrap3/js/bootstrap-editable.js
Line 154
Which is actually this line :
this.$element.data('popover').tip().addClass('editable-popover');
Btw, I'm using CakePHP, all the plugins (js and CSS) are declared etc...
So I'm running out of idea, if someone knows about it, would be cool !
Thanks !
EDIT : Problem solved, just had to reload the cache... Old script was still in it so there was compatibility problems.

Did you download the latest Bootstrap 3 ready version from: http://vitalets.github.io/x-editable/assets/zip/bootstrap3-editable-1.5.0.zip
I didn't find any problem following the steps from http://vitalets.github.io/x-editable/docs.html. See: http://jsfiddle.net/xaRbU/
Note the examples use jquery-2.0.3 (the fiddle above works with 1.9.1). Since jQuery 2 doesn't support IE8 Bootstrap requires the newest 1.x version of jQuery, see also: Updating Bootstrap to version 3 - what do I have to do?
Code used:
html:
<div class="container">
<div class="row">
superuser
</div>
</div>
javascript:
$(document).ready(function() {
$('#username').editable();
});
css:
/* create some space cause the popup shows on the top of the element */
body{padding-top:100px;}
