Fix the options in Cakephp Form Field of type radio button

Hi,

i am having Cakephp code like

<?php foreach ($viewfields as $r): 

                          if($r['Attribute']['type']=='radio')
                        {

?>

   <script type="text/javascript">
    jQuery.noConflict();
   jQuery(document).ready(function($){


    $("#"+<?=$r['Attribute']['id'];?>).each(function() { 

    type= "<?=$r['Attribute']['type'];?>";
    attribute_id="<?=$r['Attribute']['id'];?>";
if(type=="radio")
{
   var ht = $.ajax({
   type: "GET",
   url: "http://localhost/FormBuilder/index.php/forms/viewChoices/"+attribute_id,
   async: false
   }).responseText;



       var myObject = eval('(' + ht + ')');

 var data = myObject;var j=0;
 $.map(data.choices, function(i){ j++; 
 alert(i.choice);
     return i.choice;});  
         }//type==radio
        });//each
 });//jquery

 </script>


<?php


         echo $form->input('field', array(
        'type' => 'radio','legend'=>$r['Attribute']['label'],
       'separator' => '--separator--',
        'options' => array() 
   ));



 }//if php type == radio

 endforeach; ?>

alert(i.choice);/alerts me the choices for the label gender as male and female and for the label "experience as yes and no..
