fnFilter Does Not Work for IE9

I am working on an intranet project and one of the supported browsers is IE9. I am doing list box filters which triggers a javascript and calls on fnFilter to filter the table. This is only working for Firefox and Chrome. I did a search on this forum and so far the only issues that come up are changing the content-type to charset UTF-8. This did not resolve my problem. Below are portions of my code:

<meta http-equiv="content-type" content="text/html; charset=utf-8" />
<meta charset="utf-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge,chrome=1">

// Init DataTables
var _aoColumns = [{"sType": "mbname"}, {"bSearchable": true}, {"bSearchable": true}, {"bSearchable": true}, {"bSearchable": false, "sType": "string"}, null];
$('#tableBody').html(html.toString());
oTable = $('#tblPeople').dataTable({
		"sScrollX": "100%",
		"bPaginate": false,
		"bProcessing": _bProcessing,
		"bLengthChange": false,
		"sDom": 'pt<"clear">r',
		"bDeferRender": true,
		"aoColumns": _aoColumns,
		"bFilter": true,
		"aaSorting": [[NAME_COL,'asc'] ]
 });


// This is called by the dropdown filters
function filterPeople (val, col) {
	oTable.fnFilter(val, col);
}

I really need to resolve this ASAP. Please help.
