Answer 1

You have syntax error in your coffee script

Do this:

$(document).on "page:change", ->
  $('#comment-link').click ->
    alert "clicked"

Instead of:

${document}.on "page:change", ->
$('#comment-link').click ->
    alert "clicked"

Remember, indentation is most important while writing coffee script
