javascript - alternative method instead $watch in angularjs -


i have scope variable, when returns true, need trigger events or something. case, every first time, scope variable returns undefined , later returns true. in case used $watch method expected funcionality. there alternative approach same instead using $watch ?

 scope.$watch () ->     scope.initiatechild   , (value) ->     if value true       $timeout ->         scope.buildonboarding()       , 1000

you can try using angularjs $on(), $emit() , $broadcast().
