Using X-editable with CodeIgniter 3 CSRF issue

I'm using CodeIgniter 3 with CSRF enabled. I have a page that is using X-editable library http://vitalets.github.io/x-editable/index.html to do inline editing on that page.

Has anyone used X-editable with CodeIgniter and CSRF turned on?

My issue is when I have CSRF enabled I get the following CodeIgniter generated error:

<h1>An Error Was Encountered</h1>
<p>The action you have requested is not allowed.</p>
It works fine if I disable CSRF in CI.

What I do know is that I can't figure out a way to add a hidden field with the CSRF token when using the X-editable library, because the javascript library adds it's own form and form fields. I know that CI's open_form() method adds the hidden field with the CSRF token automatically, but I have no option to use that with this particular library.

Any ideas? I have been stuck on this for a few days now.

This is the config.php file in my CI project

$config['csrf_protection'] = TRUE;
$config['csrf_token_name'] = 'mycsrfname';
$config['csrf_cookie_name'] = 'csrfcookiename';
$config['csrf_expire'] = 7200;
$config['csrf_regenerate'] = TRUE;
$config['csrf_exclude_uris'] = array();
This is in the controller

$name = $this->input->post('name');
$value = $this->input->post('value');
$pk = $this->input->post('pk');
$result = $this->garage_model->editItem($name,$value,$pk);
