Unable to clear form fields after Submit in Angular - html

Question

I am new to angular. I have looked up a lot of answers on clearing form fields after submitting but none seems to work.
Here's my HTML code:
<form name="myForm" ng-submit="formSubmit()" class="form-horizontal">
<div class="form-group">
<input type="text" class="form-control" ng-model="user.FullName" placeholder="Full Name" required=""/>
</div>
<div class="form-group">
<input type="text" class="form-control" ng-model="user.Address" placeholder="Address" required=""/>
</div>
<button type="submit" class="btn btn-primary" style="background-color: purple;">Submit</button>
</form>
Here's my JS code:
var myApp = angular.module('myApp', ['ui.router']);
myApp.controller("RegisterCtrl", function ($window,$scope,$http) {
$scope.user={}
$scope.formSubmit=function(){
$http({
method:'POST',
url:'myurl',
data:$scope.user,
headers:{'Content-Type':'application/json'}
}).then(function(res){
console.log(res);
$scope.myForm.$setPristine();
$scope.myForm.$setPristine(true);
$scope.myForm='';
})
}
});
I have tried setPristine as well as setUntouched but none working.

I don't see something strange in your code, i make plnkr based on your code, the modifications i do are below. also put the plnkr sample
CONTROLLER
var myApp = angular.module('myApp', ['ui.router']);
myApp.controller("RegisterCtrl", function ($window,$scope,$http) {
$scope.user={}
$scope.formSubmit=function(){
$http({
method:'POST',
url:'myurl',
data:$scope.user,
headers:{'Content-Type':'application/json'}
}).then(function(res){
$scope.myForm.$setPristine();
$scope.user = {};
}, function(rej){ //error});
}
});

you should try
var myApp = angular.module('myApp', ['ui.router']);
myApp.controller("RegisterCtrl", function ($window,$scope,$http) {
$scope.user={}
$scope.formSubmit=function(){
$http({
method:'POST',
url:'myurl',
data:$scope.user,
headers:{'Content-Type':'application/json'}
}).then(function(res){
$scope.$broadcast('show-errors-reset');
$scope.forms.user = {};
$scope.forms.userFrom.$setPristine = true;
}, function(rej){ //error});
}
});
