How to access page control from static method in ASP .NET to write dynamic script

Thanks for your response. Yes, I've revisited the code and based on your comments, I've returned the dynamic content as well as JavaScript references from web method. I've tried to write this content using JavaScript and found that web method return value is correct. Also JavaScript did it's job and checked through alert and found ok what is required for me. But in web interface it's not reflecting the result. When I directly written the HTML code whatever written through JavaScript, it's giving the result in web interface.

Following is the Ajax Method and JavaScript Code for your review -

function AddDivContent(QCode) {
$.ajax({
type: "POST",
dataType: "json",
contentType: "application/json; charset=utf-8",
url: "DashboardSurveyDynamic.aspx/GenerateDivControl",
data: "{'QCode':'" + QCode + "'}",
success: function (success) {
var ltrContent = document.getElementById('PageBody_divContent');
alert("A");
ltrContent.innerHTML = JSON.stringify(success.d);
alert(ltrContent.innerHTML);
},
error: function (xhr, textStatus, error) {
alert("Error: " + error);
}

});
}

function AddScriptContent(QCode) {
alert("B");
$.ajax({
type: "POST",
dataType: "json",
contentType: "application/json; charset=utf-8",
url: "DashboardSurveyDynamic.aspx/GenerateDashboardScript",
data: "{'QuesCode':'" + QCode + "'}",
success: function (success) {
alert("C");
var scriptContent = document.getElementById('PageBody_divScript');
scriptContent.innerHTML = JSON.stringify(success.d);
},
error: function (xhr, textStatus, error) {
alert("Error: " + error);
}
});

When I tried to retrieve the written content through view page source from browser, no code found in respected area where I wanted to write the HTML code. Following is the HTML code for your review -

//

AddDivContent Ajax will write the HTML Code Here which has been return from web method

//


//
AddScriptContent Ajax will write the code return from web method

Let me know, whether I'm missing anything or not and How can I resolve this issue?
