SWF remains after element has been removed from DOM

Hi, I am using file reader in an angular context. In this particular example I am editing a resource with filereader. It draws the swf on the page. Then when the user navigates to a different page (this is a single page ajax app) the swf continues to lurk and is clickable by the user. The filereader plugin should be responsible for removing it when the element is destroyed.
