How to refresh styles and layout of radio buttons in jQuery Mobile?

I'm using

$("input[type='radio']").checkboxradio("refresh");  

to refresh a container of radio buttons. Except when I remove/add a radio button from/to the top or bottom, I do not get rounded corners on the new (top or bottom) radio button.

Here is the jquery ajax function that contains the code for removing a radio button:

$.ajax({
 type: "POST",
 url: url,
 data: data,
 dataType: "json",
 success: function(resp) {                              
    $("'label[for="+key+"]'").parent().remove();
}

Here is the form:

<form id="test-form">
  <div data-role="fieldcontain" id="test">
    <fieldset data-role="controlgroup">
        <input type="radio" name=开发者_如何转开发"key" id="{{a.key}}" value="{{a.key}}" 
    <label for="{{a.key}}">{{a.name}}</label>
        <input type="radio" name="key" id="{{b.key}}" value="{{b.key}}" 
    <label for="{{b.key}}">{{b.name}}</label>
        <input type="radio" name="key" id="{{c.key}}" value="{{c.key}}" 
    <label for="{{c.key}}">{{c.name}}</label>
    </fieldset>
  </div>
</form>

Call .page() on an element that is a parent of the element that doesn't render correctly.

We'll have to find a way to do it with refresh
