CheckBoxList in JavaScript Problem

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)
        {
		………..	
		………..
	  }
}

}
