I'm trying to save dynamically created elements in my application.js file to the database. Would the code look something like this?:

$.ajax({
   type: "POST",
   data: { title: 'oembed.title', thumbnail_url: 'oembed.thumbnail_url'}
});

Is there anything I'm missing? Assume that oembed.title and oembed.thubnail_url hold the values I want to save, and that title and thumbnail are the database columns.
