angularjs how can i post my form into the json - angularjs

Question

I am building my first angular app and looking to post my form into my JSON data.
This is my form:
<span ng-show="show">
<form name="inputForm" class="form-group" ng-controller="FormController as autoctrl" ng-submit="inputForm.$valid && autoctrl.addGegevens(gegeven)" novalidate>
<br>
<p> Type: <input type="text" name="type" ng-model="type" style="margin-left:52px; padding-left:5px; width:165px;" minlength="2" maxlength="10" required /></p>
<p>Bouwjaar: <input type="number" name="bouwjaar" ng-model="bouwjaar" style="margin-left:22px; padding-left:5px; width:165px;" minlength="4" maxlength="4" required /></p>
<p>Km: <input type="number" name="km" ng-model="km" style="margin-left:60px; padding-left:5px; width:165px;" minlength="2" maxlength="6" required /></p>
<p>Brandstof: <input id="select" name="brandstof" ng-model="brandstof" style="margin-left:20px; padding-left:5px;" minlength="3" maxlength="7" required/></p>
<p>Kenteken: <input type="text" name="kenteken" ng-model="kenteken" style="margin-left:22px; padding-left:5px; width:165px;" minlength="6" maxlength="9" required /></p>
<p>Datum: <input type="text" name="datum" ng-model="datum" style="margin-left:40px; padding-left:5px; width:165px;" minlength="3" maxlength="11" required /></p>
<p>checked: <input type="checkbox" name="checked" ng-model="checked" style="margin-left:28px;" required /></p>
<br>
<button class="btn btn-primary" type="submit" value="submit">Toevoegen</button>
<div>{{inputForm.$valid}}</div>
</form>
</span>
And this is my app.js:
(function(){
var volkswagenApp = angular.module('volkswagenapp',[]);
volkswagenApp.controller('VolkswagenCtrl', [ '$http' , function($http){
var vw = this;
vw.gegevens = [];
$http.get('autos.json').success(function(data){
vw.gegevens = data;
});
}]);
volkswagenApp.controller('FormController',function(){
this.gegevens={};
/* this.addGegevens = function(gegeven) {
gegeven.gegevens.push(this.gegeven);
this.gegevens={};
}*/
this.addGegevens = function(gegeven){
this.gegevens.datum = Date.now();
vw.gegevens.push(this.gegeven);
this.gegeven = {};
}
});
})();
Can somebody tell me where I am going wrong? I did the same steps as they do on codeschool.

Since you are using controllerAs you need to add the controller object to all the variables in ng-model
Example:
<input name="type" ng-model="type">
Should be:
<input name="type" ng-model="autoctrl.type">
However you can make it simpler to post a single object by making all the ng-model's properties of the same parent
<input name="type" ng-model="autoctrl.myFormModel.type">
Then when you are ready to post you simply send myFormModel
$http.post(url, this.myFormModel).then(....
Note that you should store a reference to this so you can use that reference inside any callbacks. I see you using vm but it is not defined anywhere inside FormController
