Get autocomplete selector after ajax call
<p>I am trying to find the selector of a jquery autocomplete in the "success" after making an ajax call.  In the "success" I am looking for $(this) to be $(".itemDescInput") but it is not.  How would I find that selector at that point?</p>

<pre><code>$(".itemDescInput").autocomplete({
    source: "invoices/invoice_items.php",
    select: function(event, ui) {
        var $it_desc = ui.item.value;
        $.ajax({
            type: "POST",
            url: "invoices/invoice_items_prices.php",
            data: "it_desc="+$it_desc,
            success: function(result){
                if(result != '') {
                    $(this).find("input .itemCostEach").val(result);
                }
            }
        });
    }
}); 
</code></pre>
