Unfortunately, there are quite a few things wrong with this code. But don't be discouraged! My suggestion would be to back up an learn a little more about JS / jQuery.
You should not be using jQuery to directly bind events if Controller is available. Can you explain why the code is doing this? You could just use:
"#register_call_me_now click"
You might want to read up on event delegation.
You should probably not be adding an element with an ID in this way. 3 calls to the dom element is unnecessary.
You might want to learn about closures or $.Class's this.proxy to get 'this' to be what you expect.
