jquery - validate dynamically created elements on select an option of combobox -

i using jquery validate() plugin .
hava combobox in form when user select option on new element create dynamically .
how validate new element according selected option of combobox .
in fact want first check value of combobox it's new elements created .
have solution ???

if create new element when user select option can validation right after that? (but shouldn't validate first , create new element?)

http://jsfiddle.net/ggb6c/

<div id="test">     <select id="combobox1">         <option value="1">value 1</option>         <option value="2">value 2</option>         <option value="3">value 3</option>         <option value="4">value 4</option>     </select> </div>  $("#combobox1").change(function() {     var text = $('<input type="text"></input>');     $('#test').append(text);     text.validate(); }); 

or mean want same behaviour 2 comboboxes. e.g. user selects option in combobox1, create combobox2. user selects options , create combobox3?

(in short, can rephrase question?)
