Sharing settings across methods in namespaced jQuery plugin

Question

I\'m writing a plugin and following the jQuery documentation\'s recommended practice http://docs.jquery.com/Plugins/Authoring when it comes to namespacing and multiple methods.

Like fudgy wrote you may consider setting your defaults outside the init method. I tried following that same tutorial and came up with the following code combining settings and methods, but I ran into some other disadvantage.

  (function( $ ){
     var config, methods = {
        init: function(customSettings) {
            var config = {
                debug: true
            }
            return this.each(function () {
               if (customSettings) {
                   $.extend(config, customSettings);
               }
            });
        },
        someMethod: function(arg) {
           if(options.debug) {
               // do something
               alert('debug ' + arg);
           } else {
               alert('no debug' + arg);
           }
        }
    }

    $.fn.myplugin = function (method) {
        if ( methods[method] ) {
            return methods[method].apply( this, Array.prototype.slice.call( arguments, 1 ));
        } else if ( typeof method === 'object' || ! method ) {
            return methods.init.apply( this, arguments );
        } else {
            $.error( 'Method ' + method + ' does not exist on jQuery.myplugin' );
        }
    };

})( jQuery );

But when your call it like:

$('p.one').myplugin({ 'debug' : 'false' });

For the second paragraph debug is unfortunately still false.

$('p.two').myplugin('someMethod', 'hmm!');

I first need to init the paragraph with 'true' again to be able to debug it.

$('p.two').myplugin({ 'debug' : 'true' });
$('p.two').myplugin('someMethod', 'hmm!');

Did I oversee something in the tutorial?
