How can we call angular with js? I have sample but it isn't working.

jscall(angular.element("#content").scope().sample());

I am getting this error;
"ERROR: jscall() - calling Javascript "angular.element('#content').scope().vm.vrService.refreshVrXml()" failed: ReferenceError: angular is not defined"

EDIT :
I found my answer

jscall('window.top.angular.element("#content").scope().sample());
