Hi,
 I am having scope variable like *formName*  as a  json object in parent 
controller and and watching from child controller using $watch. On 
submitting the form i am making the *formName *as null and then again 
assigning the value .But the $watch function was not working and the *formName 
*still holds the last assigned value. Like below.


In child controller
$scope.$parent.$watch('*formName*',function (formName){
}):


In parent controler

$scope.formname = null;
function onSubmit(){
//after api call
$scope.formName  = null;
$timeout(function(){
   $scope.formName = (updated data)
})
}
