There are multiple ways how to communicate between controllers.
The best one is probably sharing a service:
function FirstController(someDataService)
{
// use the data service, bind to template...
// or call methods on someDataService to send a request to server
}
function SecondController(someDataService)
{
// has a reference to the same instance of the service
// so if the service updates state for example, this controller knows about it
}
Another way is emitting an event on scope:
function FirstController($scope)
{
$scope.$on('someEvent', function(event, args) {});
// another controller or even directive
}
function SecondController($scope)
{
$scope.$emit('someEvent', args);
}
In both cases, you can communicate with any directive as well.
