Enable an asp control runat server via javascript, until this control is not enable from server   

I have seen that if I put a radiolistbutton on a page with 3 radiobutton and 
the first (as example) is not enable at design time (so server side), i 
can't enable it from javascript with something like this

var btlList = document.form1.elements["RadioButtonList1"];

btlList[0].disabled = false;


This because of its rendering in HTML

<table id="RadioButtonList1" border="0">
    <tr>

  <td><span disabled="disabled"><input id="RadioButtonList1_0" type="radio" 
name="RadioButtonList1" value="pippo" disabled="disabled" /><label 
for="RadioButtonList1_0">pippo</label></span></td>
 </tr>

<tr>
  <td><input id="RadioButtonList1_1" type="radio" name="RadioButtonList1" 
value="pluto" /><label for="RadioButtonList1_1">pluto</label></td>
 </tr><tr>
  <td><input id="RadioButtonList1_2" type="radio" name="RadioButtonList1" 
value="paperino" /><label for="RadioButtonList1_2">paperino</label></td>
 </tr>
</table>

Do you see? There's a "span" which is disabled. So from javascript i can 
enable the radioButton, but the span is still disabled, so the children.. 
radiobutton

I can solve that? PLS HELP!

Thank you all

var btn = document.getElementById("RadioButtonList1_0")
btn.disabled = false
btn.parentNode.disabled = false
