coffeescript - Coffescript show alert when clicking on element? -

-

i have code 

$ ->         $('h1').click ->       alert "i knew it!"    init()

what's wrong it?nothing happens.

not sure probablt code formatted inproperly (what important in coffeescript). callback click event must nested (otherwise passed callback empty function)

$ ->   $('h1').click ->     alert("i knew it!")    init()
