    to detect the input text change, you can do that with the help of JQuery. u should look at http://api.jquery.com/change/ here for .change() method for text inputs.

    EDIT :

    here is an on-the-fly example;

    <html>
<head>
<title>JQuery Test</title>
</head>
<body>

Name : <input type="text" id="txtName" /> <input type="checkbox" id="chxName" /><br/><br/>
Surname : <input type="text" id="txtSurname" /> <input type="checkbox" id="chxSurname" /><br/><br/>

<script type="text/javascript" src="http://ajax.aspnetcdn.com/ajax/jQuery/jquery-1.6.1.min.js"></script>

<script type="text/javascript">

$(document).ready(function(){

    $('#txtName').change(function(){

      var poo = $(this).val();
      var foo = $('#chxName');
      if(poo == 'bar'){
        if(!foo.is(':checked')) {
          foo.attr('checked','checked');
        }
      } else {
        if(foo.is(':checked')) {
          foo.removeAttr('checked');
        }
      }

    });

});

</script>
</body>
</html>

    run this example and enter ‘bar’ inside the first textbox. u will see the first checkbox has been ticked. then enter another word except ‘bar’. u will see the first checkbox has been unticked.

    Also you can consider some of the other jQuery events like keyup, keydown or keypress
