CheckBoxList in JavaScript

I have an asp:CheckBoxList named cblRoles with values. The values are coming from the database and can be in any order in cblRoles. When I check enabled “Admin” option from cblRoles my JavaScript function CheckAdmin’s IF STATEMENT executes but when I check enabled “Admin” option from cblRoles and make “Admin” option DISABLE, listControl.checked in the IF STATEMENT doesn’t execute. I want the IF STATEMENT to execute as well when the “Admin” option is checked & DISABLE

Here is my JavaScript code:


function CheckAdmin(source, args)
{
args.IsValid = false;

var cblRoles = document.getElementById('<%= cblRoles.ClientID %>');

var num = cblRoles.childNodes[0].childNodes.length;

var currentTable = cblRoles.childNodes[0];


for (var i=0 ; i<num ; i++)
{
var InnetText = currentTable.childNodes[i].childNodes[0].innerText;

var currentTd = currentTable.childNodes[i].childNodes[0];

var listControl = currentTd.childNodes[0];

if (InnetText=="Admin" && listControl.checked)
{
………..
………..
}
}

}


Here I am posting my generated SOURCE code
