  searchResult: Rxel.calc (keyword) ->
    $.getJSON "http://example.com/search.json?q=#{name}"

##
sc.message.then (message) ->
  console.log message # ==> "Hello, John"
.then ->
  sc.name = "Jane"
  sc.message
.then (message) ->
  console.log message # ==> "Hello, Jane"

##
$("input[name=keyword]").on "keyup", (e) ->
  keyword = $(@).val()
  # sc.keyword = keyword
  sc.$set "keyword", keyword

sc.$("searchResult").subscribe (result) ->
