Passing values to modal window (jqyer / bootstrap)

I am trying to pass values (TRUE OR FALSE) to fields on a modal window.
This is for "field3" and "field4"

the value shows just fine on the text fields but doesn't work well with the radio buttons. I need for the radio buttons to appear marked depending on the value. (1 or 0)

This is my modal window code:

<!-- modal window -->
<div id="edit-modal" class="modal fade" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true">
	<div class="modal-dialog">
		<div class="modal-content animated fadeIn">

<form action="attachments_SPedit.asp" method="post" class="form-horizontal" id="form1" form="form1">
<div class="modal-header">
	<button type="button" class="close" data-dismiss="modal" aria-hidden="true">×</button>
	<h3 class="modal-title">Edit attachment</h3><small>Please update the attachment information</small>
</div>
<div class="panel-body">
	<div class="ibox float-e-margins">
    	<div class="form-group"><label class="col-sm-3 control-label">Description</label>
        <div class="col-sm-9">
        <input name ="field1" type="text" class="form-control" id = "field1" placeholder="" value="" maxlength="50">
        </div>  
	</div>
    <div class="form-group"><label class="col-sm-3 control-label">Uploaded on</label>
        <div class="col-sm-9">
        <input name ="field2" type="text" class="form-control" id = "field2" placeholder="mm/dd/yyyy" value="" maxlength="10">
        </div>  
	</div>
     <div class="form-group"><label class="col-sm-3 control-label">Visible employer</label>

                    Yes</label>
                    
                  <label>

<!-- modal window end -->

This is the code that passes the values to the modal window. It works fine, the text fields show the value just fine but the radio buttons don't appear marked when the value is passed to them. Any clues ?

<script type="text/javascript">
 $(function () {
   $('#edit-modal').on('show.bs.modal', function(e) {  // NAME OF MODAL WINDOW TO OPEN 
     var $modal = $(this),
         esseyId = $(e.relatedTarget).data('id');  // SEND VALUE OF ID 
		 field4 = $(e.relatedTarget).data('field4');  // SEND VALUE OF FIELD 1
		 field3 = $(e.relatedTarget).data('field3');  // SEND VALUE OF FIELD 1
         field2 = $(e.relatedTarget).data('field2');  // SEND VALUE OF FIELD 1
         field1 = $(e.relatedTarget).data('field1');  // SEND VALUE OF FIELD 2 
		 
     $('input[name="idfield"]', $modal).val(esseyId); // SEND VALUE OF ID TO HIDDEN FIELD ID
console.log('[' + field1 + ']');// SEND VALUE TO DROP DOWN MENU
	$('#field1').val(field1); // SEND VALUE TO DROP DOWN MENU
	$('input[name="field2"]', $modal).val(field2); // SEND VALUE TO TEXT FIELD  
	$('input[name="field3"]', $modal).val(field3); // SEND VALUE TO TEXT FIELD  
	$('input[name="field4"]', $modal).val(field4); // SEND VALUE TO TEXT FIELD  
     $modal.find('.edit-content').html(esseyId);  
   });
   
 });
 </script>
