Q:

Help with 'hello world' jquery-ui modal-form?

I'm trying to display a modal form using jquery ui. I've adapted an example but I cannot get the dialog to launch. I'm sure it's very simple but can someone tell me what I'm doing wrong ?
The page displays initially but when I click on 'Create New User' nothing happens.
The code is below - also (easier to read) at http://pastie.org/1000263 .

A:

Your code worked fine when I removed .button()
   $('#create-user')
    .click(function() {
     $('#dialog-form').dialog('open');
    });

I'm not really sure what .button() does anyways. I'm not sure I've seen it before.
The javascript console in chrome said:
"Uncaught TypeError: Object # has no method 'button'"
The javascript console will be very useful for "why things don't work".
