如何在AngularJS Emit中将函数作为参数传递？

Question

I'm using the emit function in AngularJS and was wondering if it's possible to pass in a function as an argument.

Parent Controller:

$scope.$on("getChildFunction", function(event, func) {
    console.log("function is...", func);
})

Child Controller:

$scope.$emit("getChildFunction", $scope.load_function());

However, when I use the web inspector func isn't returning at all. Are functions able to be passed up to the parent scope using emit?

If you want to pass the function itself, omit the parenthesis:

$scope.$emit("getChildFunction", $scope.load_function);

If you include the parenthesis - you'll execute the function and pass the result of the function.
