JqueryUI modal dialog breaks knockoutjs bindings

The intention is for the user to click on the logo section and be presented with a modal dialog in which they can upload a new logo image, change the current logo image or delete the current logo.

At the moment, the loading image causes the page to refresh, but I am moving on to using ajax messages that handle this function to prevent the page from refreshing.

The problem I am facing is that after the image is there and the user deletes the image, the modal dialog is not updated after the jock knockout model. The image is displayed in two areas, once on the screen where it should be, and again in the modal dialog as a preview. The main src image is updated, and I can hide, but it looks like the bindings between the knockout and the dialog are dropped when jQueryUI clones the element.

I tried to use the example of the init of the post , but not a modal dialog box is displayed.

Any ideas?

HTML / Razor

<div id="logo" data-bind="cmdDialog: {id:'dialog-form', cmd:'open'} ">
    <div id="changeLogo">
        <h1 data-bind="visible: URL() == null"><span>Logo Here</span></h1>
        <img data-bind="attr: { src: URL}, visible: URL() != null"/>
    </div>
    <div id="dialog-form" data-bind="setDialog:{}">
        <img data-bind="attr: { src: URL}"/>
        <button type="button" data-bind="visible: URL() != null, deleteImage: ImageID">Remove Image</button>
        <hr/>
        <form action="uploadImage" method="post">
            @Html.HiddenFor(m => m.ID, new { data_bind = "value: ID" })
            @Html.HiddenFor(m => m.ImageID, new { data_bind = "value: ImageID" })
            <div>
                <input type="file" name="file" id="file"/>
            </div>
            <div>
                <input type="submit" value="Upload" />
                <button type="button" data-bind="cmdDialog: {id:'dialog-form', cmd:'close'} ">Cancel</button>
            </div>
        </form>
    </div>
</div>
