How to set same broadcast in two places

Question

I have a piece of code that needs to be invoked after execution of some other code. i'm using broadcast for this. I need to invoke the same code from 2 different places. Now that is not working for me. My code is

Broadcast 1

scope.$broadcast('selOrdLine', ordline);

On

scope.$on('selOrdLine', function (event, args) {
 // some code here
})

I need to invoke this code from some other place also

so I put scope.$broadcast('selOrdLine', ordline); there also. But it is returning error.

Edit

The second time when I use broadcast I'm making the ordline data using the angular.forEach loop. so I'm using $q for running the broadcast only after the data is ready like this

$q.all(orderline).then(function () {
    $scope.$broadcast('selOrdLine', orderline);
});

The error is, the broadcast is invoked multiple times. But as I use $q it should run only after the orderline data is set, right ?
