$().buttonset not working on dialog modal box

I've done a dialog box that contains a form inside it, and I would like to add some fancy items to it. I've been trying with $().buttonset() as I've done with most of my radio buttons in the application, in order to get a coherent UI for my application. The thing is that, even if following the rules specified, the buttons remain as a normal radio button, and not with the fancy interface. Do you know what could be the problem?

This is the part of the form where I want the fancy ra开发者_如何学编程dio buttons:

<div id ="Replace">
    <input type="radio" name="Replace" value = "true"  id = "ReplaceYes" 
           onclick = "setReplace(this)" />
    <label for="ReplaceYes">Yes</label>
    <input type="radio" name="Replace" value = "false" checked="checked" 
           id = "ReplaceNo" onclick = "setReplace(this)" />
    <label for="ReplaceNo">No</label>
</div> 

And then, as the previous part of code is in a partial view, invoked when showing the modal box, this is how I try to convert the buttons appearance:

$("#Replace").buttonset();

The thing is that, debugging it I've seen that it goes through that part of the code, but it doesn't do what it's meant to do. Any clue?

I had the same problem has your, after an intensive reflexion I 've found that : When you declare your Dialog box, you can specify a function called when it opens

$( ".selector" ).dialog({
    open: function() {
        $( '#buttonset' ).buttonset();
    }
});

Updated: I had never used .buttonset() before, in any case it works against your markup, you can see a demo here. This demo uses the same code as the question:

$("#Replace").buttonset();

Make sure you're including the jQuery UI CSS correctly, and that your IDs are unique, if they are not you'll get some real funny behavior, and should switch to a class. Also, ensure that this part of your view is in the DOM when it runs, e.g. is it inside a document.ready event handler like this?

$(function() {
 $("#Replace").buttonset();
});
