[jQuery] Custom Callback not using jQuery object

[jQuery] Custom Callback not using jQuery object


I have built a custom callback into my plugin, here is an example:
$.fn.matrixStatus = function(options) {
var defaults = {
urlSuffix: '?action=live',
     onComplete: function() {}
};
var options = $.extend(defaults, options);
return this.each(function() {
var obj = $(this);
     var itemDesc = obj.attr('rel');
var itemId = obj.attr('id');
var itemHref = obj.attr('href');
obj.click(function() {
if (!itemDesc == '') {
         var question = confirm('Are you sure you want to change the status
of "'+itemDesc+'"?');
     } else {
         var question = confirm('Are you sure you want to change the
status?');
     }
if (question) {
$.ajax({
type: 'POST',
url: itemHref + defaults.urlSuffix
});
         // Run our custom callback
         defaults.onComplete();
}
return false;
});
});
};
For some reason when I try to use that function for a custom callback,
it won't allow me to get the jQuery object that the plugin is
targeting, so using $(this) within the onComplete function doesn't
work and give me errors. Any idea why this would be?
