JQuery Autocomplete issue with .net mvc - asp.net-mvc-3

Question

I'm having a problem using autocomplete in conjunction with other javascript libraries that I need in my project.
When I run this simple example it works fine in the first time. It shows the autocomplete window perfectly, but if I try to change the word I'm typing it generates this error in Chrome:
Uncaught ReferenceError: pos is not defined on the file jquery-1.4.4-vsdoc.js:2495
This is the code:
$(function () {
var availableTags = [
"ActionScript",
"AppleScript",
"Asp",
"BASIC",
"C",
"C++",
"Clojure",
"COBOL",
"ColdFusion",
"Erlang",
"Fortran",
"Groovy",
"Haskell",
"Java",
"JavaScript",
"Lisp",
"Perl",
"PHP",
"Python",
"Ruby",
"Scala",
"Scheme"
];
$("#txtPesquisar").autocomplete({
source: availableTags
});
});
and I lead all these javascripts in my master page for my project.
I don't know why I get this error.
<link href="<%= Url.Content("~/Content/jquery-ui-1.10.1.custom.css") %>" rel="stylesheet" type="text/css" />
<script src="<%= Url.Content("~/Scripts/jquery-1.9.1.js") %>" type="text/javascript"></script>

<script src="<%= Url.Content("~/Scripts/jquery.Jcrop.min.js") %>" type="text/javascript"></script>
I red something here in the forum it could be a postback functions but I don't know how to figure it out.
Thanks for your help

did you notice? the file vsdoc it's a little bit older than jQuery version, even you should remove the vsdoc.js from the runtime version.
if open the vsdoc you can find with this note.
