$.ajax within jquery plugin not updating variable - ajax

Question

Fiddle: http://jsfiddle.net/gpTpK/
The issue I am having is that the title variable is not updated/changed when the $.ajax is executed, I know that the ajax call is working as I have tried replacing the line
title = $(xml).find("title").text();
with
console.log($(xml).find("title").text());
and sure enough it does return the title however when using the orginal line the variable title doesn't change
I have tried and it does work putting the ajax call outside (function($){})(jQuery);
(function($) {
$.fn.getPost = function(options) {
var $this = $(this);
var defaults = {
method: "html",
blogID: "",
postID: "",
done: null
};
var options = $.extend(defaults, options);
var title;
$.ajax({
type: "GET",
url: "http://www.blogger.com/feeds/724793682641096478/posts/default/3551136550258768001",
dataType: "xml",
dataType: 'jsonp',
success: function(xml) {
title = $(xml).find("title").text();
}
});
return $this.each(function() {
if (options.done) {
options.done.call(undefined, title);
}
});
};
})(jQuery);
I have tried the below and i have also tried wrapping the ajax in a function such as getTitle(){ajax code here with return title;}
(function($) {
$.fn.getPost = function(options) {
var $this = $(this);
var defaults = {
method: "html",
blogID: "",
postID: "",
done: null
};
var options = $.extend(defaults, options);
var title;
getAjax();
return $this.each(function() {
if (options.done) {
options.done.call(undefined, title);
}
});
function getAjax() {
$.ajax({
type: "GET",
url: "http://www.blogger.com/feeds/724793682641096478/posts/default/3551136550258768001",
dataType: "xml",
dataType: 'jsonp',
async: false,
success: function(xml) {
title = $(xml).find("title").text();
}
});
}
};
})(jQuery);

sorry, I have spent ages trying to figure it (I didn't ask out of laziness :P), regardless here's the solution for those interested :)
(function($) {
$.fn.getPost = function(options) {
var $this = $(this);
var defaults = {
method: "html",
done: null
};
var options = $.extend(defaults, options);
var title;
var sorf;
$.ajax({
type: "GET",
url: "http://www.blogger.com/feeds/724793682641096478/posts/default/3551136550258768001",
dataType: "xml",
dataType: 'jsonp',
success: function(xml) {
title = $(xml).find("title").text();
sorf = 1;
},
error: function(){
sorf = 0;
},
complete: function() {
returnvals(sorf);
}
});
function returnvals(sorf) {
if(sorf){
//success
return $this.each(function() {
if (options.done) {
options.done.call(undefined, title);
}
});
}else{// failure}
}
};
})(jQuery);
