Hi guys, I can’t understand why when I add $ionicHistory to my controller, the form in the view of that controller gets deleted. Any help?

This is my controller

.controller('ScaleNewCtrl', function($scope, $rootScope, $http, $ionicHistory ) {

 $scope.ruta= null;
 $scope.origen= null;
 $scope.destino= null;
 $scope.fecha_salida= null;
 $scope.fecha_llegada= null;
 $scope.tac_salida= null;
 $scope.tac_llegada= null;
 $scope.tiempo_total= null;
 $scope.combustible= null;
 $scope.fuel_bs= null;
 $scope.fuel_dls= null;
 $scope.tax_bs= null;
 $scope.tax_dls= null;
 $scope.observaciones= null; 


$scope.salvar = function () {

        



        var url = "http://localhost:3000/newscale";
        
        var numero = $rootScope.flightid;
        
        $http.post (url,{ruta: $scope.ruta,
                         origen: $scope.origen,
                         destino: $scope.destino,
                         fecha_salida: $scope.fecha_salida,
                         fecha_llegada: $scope.fecha_llegada,
                         tac_salida: $scope.tac_salida,

                    })

            .then(function(resp) {
                console.log(resp);
            }, function(err) {
                console.error('ERR', err);
                // err.status will contain the status code
            });
            
            alert('Escala Enviada');
