like ng-change on fileinput

[gtreimun]

Hi! I am trying to detect when the input state changes, for example when it is undefined or when it has an image, something like "ng-change", is there any function like this?
Thanks for your time.

For now, you can just use $watch against your $scope variable defined with the lf-files attribute (I watch the .length property of that object).

I got the same problem here, I cant watch the $scope.files

$scope.$watch('files.length',function(newVal,oldVal){
   if ( $scope.files && $scope.files[0] && $scope.files[0].lfFileName) {
      // files has changed and has a valid entry to act on
   }
});
