Jquery retrieve values of Dynamically created elements - forms

Question

I have a html page with a form.
The form has Div which gets populated dynamically with Input elements like text box,radio,checkbox etc.
Now I want to retrieve the values of these dynamically created elements in the Html page,so that i can submit it to a page.
//HTML PAGE
<script type="text/javascript">
$(function() {
populateQuestions();
});
$("#submit_btn").click(function() {
// validate and process form here
//HOW TO ??retrieve values???
var optionSelected = $("input#OptionSelected_1").val();// doesn't work?
// alert(optionSelected);
postAnswer(qid,values);//submit values
showNextQuestion() ;// populate Div Questions again new values
});
</script>
<form action="" name="frmQuestion">
<div id="Questions" style="color: #FF0000">
</div>
//Question DIV generation script example radio buttons
//questionText text of question
//option for question questionOptions
// **sample call**
var question = createQuestionElement("1","MCQ", "WHAT IS ABCD??", "Opt1$Opt2$Opt3");
question.appendTo($('#Questions'));
function createQuestionElement(id, type, questionText, questionOptions) {
var questionDiv = $('<div>').attr('id', 'Question');
var divTitle = $('<div>').attr('id', 'Question Title').html(questionText);
divTitle.appendTo(questionDiv);
var divOptions = $('<div>').attr('id', 'Question Options');
createOptions(id, "radio", questionOptions, divOptions);
divOptions.appendTo(questionDiv);
return questionDiv;
}
function createOptions(id, type, options, div) {
var optionArray = options.split("$");
// Loop over each value in the array.
$.each(
optionArray, function(intIndex, objValue) {
if (intIndex == 0) {
div.append($("<input type='" + type + "' name='OptionSelected_" + id + "' checked='checked' value='" + objValue + "'>"));
} else {
div.append($("<input type='" + type + "' name='OptionSelected_" + id + "' value='" + objValue + "'>"));
}
div.append(objValue);
div.append("<br/>");
}

You are creating the same input multiple times, since you're splitting the option array, you're making this:
<input type='radio' name='OptionSelected_1' checked='checked' value='Opt1'>
<input type='radio' name='OptionSelected_1' value='Opt2'>
<input type='radio' name='OptionSelected_1' value='Opt3'>
You are currently fetching by ID with the #, instead you want to fetch by name and get the :checked item, like this:
var optionSelected = $("input[name=OptionSelected_1]:checked").val();
