buttonset doesn't work in a modal dialog box

buttonset doesn't work in a modal dialog box

Hello everyone! I've done a dialog box that contains a form inside it, and I would like to add some jquery 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 IU 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 radio buttons:

  1. <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>

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:

  1. $("#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've tried to call it from document.ready event, also from the open event in the dialog box, with no results

Thanks everyone for your attention, vikitor
