</head>

<body>
<script type="text/javascript">

$(document).ready(function(){

var newTextBoxDiv = $(document.createElement('div'))
     .attr("id", 'TextBoxDiv' + counter);

newTextBoxDiv.after().html('<label>Q'+ counter + ' : </label>' +

    $("#TextBoxDiv" + counter).remove();

 });

 //$("#getButtonValue").click(function () {

// var msg = '';
//for(i=1; i<counter; i++){

You have to define the var counter before document.ready

Does not work: 
$(document).ready(function () {
        var counter = 2;//question



  Works:
var counter = 2;//question
$(document).ready(function () {

EDIT: counter is only global is defined outside $(document).ready

Try append newTextBoxDiv in your code:

   .... var newTextBoxDiv = $(document.createElement('div'))...
         .attr("id", 'TextBoxDiv' + counter);
    $('body').append(newTextBoxDiv);
  ...  newTextBoxDiv.after().html('<label>Q'....

$('body').append(newTextBoxDiv);
