What is the problem when updating data in contoller us?

Question

Angular

There is a piece of code:

controllerAs: 'source'
controller: ($scope)->
    source = this
    $rootScope.$on 'update-source', () ->
        source.sources = User.getData('moneySource')

during the event, some data is updated
, so, the data is updated only on the PC, but on the ipad there is no one.
Has anyone encountered a similar one?
