Integrate Codeigniter and Filterable - codeigniter

Question

I'm trying to integrate Codeigniter and Filterable but I cant find much information about it. I have a page with many results and I want to filter the results, for example by the column "name" or "id". I have worked with Filterable before, but never had to do it with Codeigniter.
I tried to put the files on the root. Also in the folder "Application", even tried putting it on the same folder as the view. But in any of these cases I cannot link the files and get it to work.
The ways I've been trying to link the scripts are the following:
<script src="<?php echo site_url('src/filterable.js')?>"></script> This was with the scripts in application folder
<script src="./src/filterable.js"></script> Scripts on root
<script src="<?php echo site_url('admin/src/filterable.js')?>"></script> Scripts on view folder
Is there another way to achieve this? Or maybe another library I could use for it?

Here is how I like to deal with assets.
I create an helper called assets_helper in application/helpers/
<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
if ( ! function_exists('js'))
{
function js($nom)
{
return '<script src="' . base_url() . 'assets/js/' . $nom . '.js" type="text/javascript" ></script>';
}
}
//This is only the part that handle js as it is what's bothering you
Here is the full helper I use : http://pastebin.com/ujETEXJ4
After that, at the same level as index.php I create those folder :
|-Application
|-System
|-index.php
|-Assets
|- css
|- sass
|- images
|- js
Put all the js file you need in your new js folder.
In my application/config/autoload.php I add my new helper
$autoload['helper'] = array('assets', ...);
Finally, in the footer of my page(s) :
<?= js('myjsfile'); ?> //I did not forgot the extension, it's how it works :)
Which will give at the end :
<script src="http://www.example.com/assets/js/myjsfile.js" type="text/javascript" ></script>

Thanks AdrienXL for your answer. I tried to follow your suggestion but in the end I couldn't make it work. For some reason Codeigniter didn't recognize the files I tried to reach.
So after a long searching I ran across a library called Datatables http://www.datatables.net/ it has the option to load the scripts locally or remotely, so just added the link to the scripts needed to the type of filter I had to implement and in the end this last option was what allowed me to make the filters work.
