jquery plugin on dynamic data

I have a page which outputs an unordered list from the database.  A sample of the output is below.  When the data is placed statically on the page the jquery.treeview works perfectly, but when attempting to post the data dynamically (either in page_load or OnInit) it gives the error "Object doesn't support this property or method".  It doesnt' matter if the code is on the page statically, or if it's placed dynamically:          
$(document).ready(function() {
        $('ul:first').treeview(); });
}
or
 $(document).ready(function() {
        $('$tree').treeview(); });
}

both give the same error.  My question is: How can I make this work, so that the jQuery object is attached to the UL on the page?  I believe that the UL needs to be added to the DOM, but using the onInit it should already be there, shouldn't it?

Thanks,
Geoff

To select the <ul> id you should use the '#':

$('#tree')...

Maybe you mistyped in your question.

Are you sure the dynamically generated ul has the id assigned to it?

I am.  I have tried using the straight ID and the ClientID.  Neither works.  And you're right:  I mistyped the question thanks.

I found a cool dynatree plugin. Maybe it's helpful?

the problem isn't generating the tree. I have tried 3 different plugins (Collapse, Treeview and JSTree) all the with same effect.  Somehow it's not recognizing the UL as being part of the DOM so the jquery isn't binding to it.
