easyui "Object doesn't support this property or method" in ie 9

Question

Hello I am using easyui in my web based application. It works fine chrome and firefox but in IE it gives me "Object doesn't support this property or method" error for easyui .window('open') method. The code is below: Thanks..

EDIT: I am including jquery after easyui library. Can this cause the problem?

 function init() {

                           var mesaj_text="<div style='margin-top:20px'>
<label style='font-size:13px;margin-left:55px'>Harita Yükleniyor</label><br> "; 
                            $("#mesajWindow").html(mesaj_text);
                            $("#mesajWindow").window("open"); //this is the line giving error


 //.........code continues//
