AngularJS – Access to child scope

Scopes in AngularJS use prototypal inheritance, when looking up a property in a child scope the interpreter will look up the prototype chain starting from the child and continue to the parents until it finds the property, not the other way around.

In a nutshell: You cannot access child scopes from a parent scope.

Your solutions:

1. Define properties in parents and access them from children (read the link above)
2. Use a service to share state
3. Pass data through events. $emit sends events upwards to parents until the root scope and $broadcast dispatches events downwards. This might help you to keep things semantically correct.
