How do I pass data from button to coffeescript function?

Question

I am a newbie to web development and have following basic question.

My Html looks like this:

<a class="btn-select" data-myId="10091" data-myDescr="The thing we delete">Click me!</a>

My coffee script looks like this:

$(document).on 'click', '.btn-select', ->
requestId = $(this).data('myId');
alert 'hello ' + requestId;

But when I click the button, I get "hello undefined". What am I missing here?

HTML5 data-attrs are required by the spec to be lowercase.

Use: $(this).data('myid')
