CoffeeScript loop through methods

I have an object literal that I'm using to group methods. I'd like to be able to call a whole group of methods easily, like so:

group =
  methodA: (str) ->
    console.log str + "from method A"

  methodB: (str) ->
    console.log str + "from method B"

for method in group
  method "hello"

# should log to console:
# "hello from method A"
# "hello from method B"

When I try this it doesn't seem to work. What am I missing / how should you go about looping through a group of methods like this?

for ... in compiles down to a for loop that assumes you are looping over an array - use for own ... of instead:

group =
  methodA: (str) ->
    console.log str + "from method A"

  methodB: (str) ->
    console.log str + "from method B"

for own method of group
  group[method] "hello"
