Jquery addRow and autocomplete - jquery-ui

Question

I have a table I would like to use autocomplete on a column.
(medSearch is the class set for this column)
I use the Jquery's autocomplete code
autocomp_opt={
source: function(request,response){
var myTable = [];
var searchStr = $(".medSearch").val();
if (searchStr.length>2)
{
alert(searchStr);
var soapEnv = "... searchStr.....";
$.ajax(
{
.............
Then I use Cloud Gen's addRow javascript.
$(document).ready(function(){
$(".addRow").btnAddRow(function(row){row.find(".medSearch").autocomplete(autocomp_opt)});
$(".delRow").btnDelRow();
$(".medSearch").autocomplete(autocomp_opt); //end autocomplete
}); //end document. ready
However, the autocomplete does not work properly with newly added row's column.
The user's input in this new row's column is not taken for the autocomplete query.
It always takes the first row's column content as the input.
I think it's because the jQuery always takes the first item which has class '.medSearch'. Then it does not take the current row's user input.
I don't know how to fix it.
Thank you for your help in advance!
My further question:
Actually, this my further question (it is too long for a comment)
I have two more columns with class identifier medCode and medDin, they need to be populated by the autocomplete result:
success: function(xml){
//alert($(xml).text());
//traverse the xml
var xmlItem = $(xml).find("*").eq(0);
//alert($(xmlItem)[0].nodeName);
var xmlMedItemArr = $(xmlItem).children().children().children();
//alert("Phyiscian Items: "+$(xmlPhyItemArr).length);
// go through each of them
$(xmlMedItemArr).each(function()
{
//do what? get each text
var childList = $(this).children();
myTable.push({
label: $(childList[0]).text() + " - " + $(childList[2]).text(),
value: $(childList[0]).text(),
din: $(childList[2]).text(),
code: $(childList[1]).text()
});
});
select: function(event,ui) {
$(".medCode").val(ui.item.code);
$(".medDin").val(ui.item.din);
},
But as the previous problem, after I select an item from the list of autocomplete result, then the two columns of all rows will be set to the same value.
How can this be done correctly?
Thank you very much for your help!
Here is the html for the table part. (we use ebase xi as the platform. It is a drag and drop web development tool. It will generate the html and some of the script automatically. You will see in the html code)

Answer 1

Use:
var searchStr = request.term;
instead of what you currently have.
The existing code:
var searchStr = $(".medSearch").val();
Reads the value of the first element that meets the selector .medSearch

Answer 2

Thank you for all your help.
I have the correct value now by using the following code:
$(this).closest('tr').find(".medCode").val(ui.item.code);
$(this).closest('tr').find(".medDin").val(ui.item.din);
Thanks,
