jQuery change Radio Button value..weird one

I have this weird problem, may be i am overlooking something but this is making me crazy. In my application i don't want user to select more than 30 items so after 30 if user clicks further radio button i don't want him to do so.

Problem is if i get the name of radio button by jquery and then set the value of that radio button , it doesn't work but if i hardcode the same name then it does work

Here is the Jsfiddle example. http://jsfiddle.net/s7GeZ/2/

HTML:

<span class="radiobut4" >
  Ignore <input type="radio" value="ignore" name="art_52643" id="52643" >
  Visible <input type="radio" value="visible" name="art_52643" id="52643" >
  Invisible <input type="radio" value="invisible" name="art_52643" id="52643">
</span>

Java Script: 

$('input:radio').live("change",function (event){
var radioName = $(this).attr("name");
    alert(radioName);
    $("input:radio[name='+radioName+'][value ='ignore']").prop('checked', true);
   // $("input:radio[name='art_52643'][value ='ignore']").prop('checked', true);

});

Just comment/uncomment last two lines to see the problem.

Any kind of help would be appreciated.

You need to specify the name of the radio, you are selecting the radio with the name "+radioName+" which is not what you want. Try this:

$("input:radio[name='"+radioName+"'][value ='ignore']").prop('checked', true);

Mismatched quotes, change :

$("input:radio[name='+radioName+'][value ='ignore']").prop('checked', true);

to

$("input:radio[name='"+radioName+"'][value ='ignore']").prop('checked', true);

To concatenate the variable into the selector.
Also note that radios with the same name is a group, and only one can be checked at a time, radios with the same ID is just invalid markup.
