Why doesn't ng-repeat detect parent scope function?

Question

Why do I have to use

e in $parent.parentScopeFunc()

instead of

e in parentScopeFunc()

when

{{ parentScopeValue }}

works fine for displaying parent scope members in a template?

Answer 1

You're either overriding that function in whichever directive it's failing in or the function is not initialized in the parent scope until after the child scope is created.
