JQuery :: Dynamically Filled SRC In Embed Tag Not Showing Flash

This code here works if the src is filled with my videolink
<object width="620" height="348">
<param name="allowfullscreen" value="true"/>
<param name="allowscriptaccess" value="always"/>
<embed src="myvideolink...." type="application/x-shockwave-flash" allowfullscreen="true" allowscriptaccess="always" width="620" height="348"/>
</object>

Now my next step is to fill it via javascript
$('a.videolink, a.videobutton, a.articlevideobutton').click(function(event){
event.preventDefault();
$('.video object embed').attr('src', $(this).attr('href'));
});

But this isn't working... empty flash is displayed. But the generated source code seems ok. The href of the link is in the src attribute of the ebmed tag. Source code is correct again but still not playing my video
$('a.videolink, a.videobutton, a.articlevideobutton').click(function(event){
event.preventDefault();
$('.video').append('<object width="620" height="348"><param name="allowfullscreen" value="true"/>
<param name="allowscriptaccess" value="always"/>
<embed src="'+$(this).attr('href')+'" type="application/x-shockwave-flash" allowfullscreen="true" allowscriptaccess="always" width="620" height="348"/></object>');
});
