Answer 1

function is misspelled (it's typed fucntion in your code)

:)

Answer 2

you can do it in this way also , but it requires jquery.

$("#id").change(function(){
    if ($(this).is(":checked")){
      alert("checked");
    }
    else{
      alert("not checked");
    }
 });

u can convert it to coffee script also. see: http://js2coffee.org/ copy and paste this code and you will get coffee script
