How do I use uniqueId() jquery ui

Question

It seems jquery ui is loaded because when i run

    $(function(){
      // did the UI load?
      console.log($.ui.version);
    });

the JS console returns 1.10.3

I am using the gem https://github.com/joliss/jquery-ui-rails (most recent) and https://github.com/rails/jquery-rails version 2.1.4

I am trying to generate unique IDs for each youtube embed's iframe

$(".youtube_embed iframe").each.uniqueId();

am i doing it right? I get this error in the JS console:

Uncaught TypeError: Object function ( callback, args ) {
    return jQuery.each( this, callback, args );
} has no method 'uniqueId' 1:938
(anonymous function)

You should iterate each matching element and assign each element an unique id.

$(".youtube_embed iframe").each(function() {
    $(this).uniqueId();
});
