How to clear form after post? - angularjs

Question

I'm creating an app using Ionic. After send values of form I want to clear form but I can't do this.
How could I do this ?
form
<form name="Empresa">
<div class="list">
<label class="item item-input"
ng-class="{'has-errors':Empresa.nomeemp.$invalid, 'no-errors':Empresa.nomeemp.$valid}">
<input type="text"
placeholder="Nome"
name="nomeemp"
ng-model="Empresa.nome"
ng-required="true">
</label>
<div class="error-container"
ng-show="(Empresa.nomeemp.$dirty || !Empresa.nomeemp.$pristine)"
ng-messages="Empresa.nomeemp.$error">
<div ng-messages-include="templates/form-errors.html"></div>
</div>
</div>
<button type="button" class="button button-block button-energized"
ng-disabled="Empresa.$invalid" ng-click="addEmpresa(Empresa);">Cadastrar</button>
</form>
controller
$scope.addEmpresa = function(Empresa){
var _pathFile = document.getElementById("smallimage").src;
var _fileName = _pathFile.substr(_pathFile.lastIndexOf('/') + 1);
if(_fileName === 'no-image.png'){
$ionicLoading.show({ template: APP_MESSAGES.escolhaImagem, noBackdrop: true, duration: 2000 });
}else{
$ionicLoading.show();
EmpresaAPIService.addEmpresa(Empresa).then(function (data) {
$ionicLoading.hide();
var retorno = JSON.parse(data.response);
if(retorno.status === 0){
$ionicLoading.show({ template: retorno.msg, noBackdrop: true, duration: 2000 });
}
if(retorno.status === 1){
//clear form
delete Empresa;
Empresa.$setPristine();
Empresa.$setUntouched();
$ionicLoading.show({ template: retorno.msg, noBackdrop: true, duration: 2000 });
}
}, function (err) {
$ionicLoading.hide();
}, function (progress) {
// PROGRESS HANDLING GOES HERE
});
}
}

Answer 1

In your controller after you do your submission logic, set $scope.Empresa.noma = ''; as that's what is being bound to your form in your application.
edit: setPristine() should also work.
