In MVC 4 I got an /Book/Create page. In this page there is an EditorTemplate with the following code:

<input type="file" name="file_upload" id="file_upload" />

Also I’ve made a javascript file which contains:

$(document).ready(function () {
    $('#file_upload').uploadify({
        swf: '/Content/Flash/uploadify.swf',
        debug: true,
        auto: false
    });
});

Now I’m using Uploadify 3.2 with the .swf file and everything works fine.
Except for the initialization of the page, first /Book/Create is called.
Then after this /Book/ is called (the Index action).

Firebug says the following:

I think it has something to do with the button_image_url in the swf debug. But even if I set the buttonImage property in the javascript it doesn’t change.
