jQuery modal window removes elements from my form

Question

jQuery, when i use it to create a modal window which contains form elemets, it takes out those elements when i submit the form.

example of the form:

<form enctype="multipart/form-data" action="/system/article/add/" class="from" method="post"> 

    <label for="article_title" class="required">Title:</label> 

    <input class="formfield" id="article_title" name="article_title" value="" type="text"> 

    <label for="url" class="required">Url:</label> 

    <input class="formfield" id="url" name="url" value="" type="text"> 

    <div id="add_photo" style="width: auto;" class="ui-dialog-content ui-widget-content"  title="Add Photo"> 
        <label for="photo_title" class="optional">Photo title:</label> 
        <input class="formfield" id="photo_title" name="photo_title" value="" type="text">
        <label for="photot" class="optional">Photo thumb:</label> 
        <input type="file" name="photot" id="photot" class="formfield">
        <label for="photo_checkbox" class="optional">Include lighbox?</label> 
        <input name="photo_checkbox" value="0" type="hidden"> 
        <input class="checkbox" id="photo_checkbox" name="photo_checkbox" value="1" type="checkbox"> 
        <label for="photo_big" class="optional">Photo:</label> 
        <input type="file" name="photo_big" id="photo_big" class="formfield"> 
    </div>
</form>

exaple of JS:

<script>
$(document).ready(function(){
    $("#add_photo").dialog({
        autoOpen: false,
        buttons: {
            "Ok": function() {
                $(this).dialog("close");
            }
        }
    });
});

So what i nocited during the inspetion via firebug, is that jquery actually removes my form elements within #add_photo and puts them outside the form in DOM, so even tough in html the modal dialog is within my form, in DOM it isn't ....

An this is the reason why i'm having the issue!

Have anyone encountered simmilar problem?

Any solution?! Thank you very much!

From http://blog.coreycoogan.com/2010/12/01/jquerys-dialog-and-form-problems/

Tie it to the form by doing $("mydialog").parent().appendTo($("form:first")).

Note that you have to this call after you already called $("mydialog").dialog()
