SELECT2 empty results - ajax

Question

I'm creating a simple select2 search box with a remote request to a php page.
I choosed to use "json" instead of "jsonp" and it seems correctly working.
The problem is that the results are white: no writes as element list.
In the image that I cannot post because "I need at least 10 reputation to post"... -.-
You could see the input box with the letter "d" and:
no loading icon (because the search has correctly ended)
no "Search" write (because the search has correctly ended)
the search box height is exactly for 2 results and you can select the results but the text is invisible.. you see just the blue selection..
The code follows:
function MultiAjaxAutoComplete(element, url) {
$(element).select2({
minimumInputLength: 1,
ajax: {
url: url,
dataType: 'json',
data: function(term, page) {
return {
q: term,
page_limit: 10
};
},
results: function(data, page) {
return {
results: data
};
}
},
formatResult: formatResult,
formatSelection: formatSelection,
initSelection: function(element, callback) {
var data = [];
$(element.val().split(",")).each(function(i) {
var item = this.split(':');
data.push({
id: item[0],
title: item[1]
});
});
//$(element).val('');
callback(data);
}
});
};
function formatResult(movie) {
return '<div>' + movie.title + '</div>';
};
function formatSelection(data) {
return data.title;
};
MultiAjaxAutoComplete('#advertiser', '/AJAXController');
and the returned json data is the following
[{"id":"12889","title":"Donnie Darko" },
{"id":"8", "title":"Another title"}
]
PS: I got two results because, at the moment, I'm returning the json data as direct output text with "echo <<< EOF ..."
Thank you,
Mauro

var data = [
{ "id":"12889", "title":"Donnie Darko" },
{ "id":"8", "title":"Another title"}
]
$(element).select2('data', data);
