binding to angular strap datepicker events when they get triggered

I'm using angular strap datepicker and I want to execute some of my own logic when the datepicker opens up and closes.

How can I recognize these events inside my controller, and bind to them?

and not just to the datepicker events, but any of angular straps events for that matter.

An example of what I want to do:

Let's say you want to get the selected date in your controller and do something with it:

Add this to your controller:

$rootScope.$watch('datepickerDateSelected', function(date){
    // do whatever you want with the date parameter here
});

And modify the datepicker directive $scope.select method, like this:

scope.$select = function (date) {
    $rootScope.datepickerDateSelected = date; // ADD THIS
    $datepicker.select(date);
};

[ UPDATE ]

Using $broadcast/$on. Modify the directive ($datepicker.show and $datepicker.hide methods) like this:

$datepicker.show = function(){
    ...
    $rootScope.$broadcast('opening'); // ADD THIS
    ...
}

 $datepicker.hide= function(blur){
    ...
    $rootScope.$broadcast('closing'); // ADD THIS
    ...
}

And in your controller, add this (you don't need to $watch anything):

$rootScope.$on('opening', function(event, data) { console.log("it's opening!"); });
$rootScope.$on('closing', function(event, data) { console.log("it's closing!"); });

It worked in my case, but you may want to check this: Working with $scope.$emit and $scope.$on (see answer from zbynour)

If you don't want to use $broadcast/$on (see the comments), just use $watch like in the first example instead.

I checked the code for AngularStrap's datepicker. They provide a $datepicker service which I thought could be decorated to achieve what you wanted, but this should be done in the config phase of your app, and the service would require a DOM element to be initialized. Thus, I think this solution is not feasible.

Anyway, I looked at Angular-UI's datepicker, and it provides attributed to specify functions to use for the open and close events. It would be much easier to use those and emit your events there.
