JQuery IE Problem

Hi. I use jQuery Dialog. In FireFox and Chrome work it perfect, but not in
IE ( I use IE 10 ). I have following javascript error:

SCRIPT438: Object doesn't support this property or method à„dialog“

dialoglink.js, line 9 character 14

The code of dialoglink.js

(function( $ ) {

T5.extendInitializers(function(){

function init(spec) {

$('#' + spec.triggerId).click(function(e) {

e.preventDefault();

jQuery('#' + spec.dialogId).dialog('open');

return false;

});

return {

dialogLink : init

};

});

}) ( jQuery );

How can I solve the problem?
