[jQuery] Drag/Drop works, but not after loading via a menu into my content div?


Hi all,
i am a beginner with javascript and finally found out how to drag the
content (a playingcard) from one div to another one.
it works when i load the page and include the content inside a content
div, but.....
Normally i have a indexpage with a content div.
I use a menu, which loads stuff in my content div like:
$('#nav li a').click(function(){
          if($(this).attr('href') === 'http://www.helenaweb.nl/
Klaverjassen/')
     {
     return true;
     }
     else
     {
     var ModToLoad = $(this).attr('href');
             $("#content").load(ModToLoad);
return false;
}
});
The cardgame is then loaded inside content div, but drag/drop does not
work
When i directly include the cardgame in the content div (instead of a
welcom message) the it works fine!
So, its exact the same content, because it is the same source file!
So, it does work well, but not after i load the code via my menu,
What am i doing wrong?
Thanks in advance for helping!
