eip.js - Basic edit in place plugin in jQuery

Question

I'm using this edit in place jQuery plugin.

I'm trying to set the Ajax request to the back-end server with details. But it didn't work, it seems the plugin eip.js missed after the Submit function.

Also how can I get the ID of the clicked HTML tag inside this call function to send it by Ajax?

I've tried some code like

$('.editable').editable({
    onChange: doAjax,
    onSubmit : function(content) {
        alert("Yes, can replace with Ajax code...");
    }
});
