jquery change event not working with IE6

It is indeed quite unfortunate that my client still uses IE6.
using jquery 1.4.2

The problem is that I open a window using a click event and do some edit operation in the new window.
I have a 'change' event attached to the row of a table which has input fields. Now when the window loads for the first time and I make a change in the input for the FIRST time, the change event does not fire. however, on a second try it starts working.
I have noticed that I e.g. I run a dummy page, i.e. create a new page(i work with visual studio) and run that page individually , the 'change' event works just fine.

what it going on? and what can i do, besides going back to 1.3.2 (by the way that doesn't work either, but haven't fully tested it yet)

<!--HTML-->
<table id="tbReadData">
<tr class="nenDataRow" id="nenDr2">
 <td>
 <input type="text" class="nenMeterRegister"  value="1234" />
  </td>
<tr />
<table>

<script type="text/javascript">
$(document).ready(function(){
 $('#tbReadData').find('tr').change(function() {
alert('this works');
}
});
</script>

Select allOpen in new window
