HttpPost generating results but not sending back to angular controller - json

Question

I’ve been battling this problem now for a few hours, and have tried several solutions (including using dataset, datareader to access the data, converting the datareader/dataset into a list of objects and then sending the result as a Json. I’ve also tried using Json.Net and a replacing the $http with an AJAX call, all to no avail.
In an MVC4 project, I’ve detailed an angular controller to retrieve data from our ACCESS database. An $http request is sent to the (local)server, received, and executed. The results generated, however, are not received back by the angular controller.
Any and all help will be greatly appreciated
This is the method:
[HttpPost]
public JsonResult GetCatalogueItems(string get)
{
JsonResult toReturn = null;
string cs = ConfigurationManager.ConnectionStrings["connStringPT"].ConnectionString;
OleDbConnection cn = new OleDbConnection(cs);
string queryStart = " SELECT catNum, testName, price, comments FROM table_catalog WHERE ";
DataSet ds = new DataSet();
try
{
List<ptProductModel> listToReturn = new List<ptProductModel>();
string query = queryStart + get + "=true;";
cn.Open();
OleDbCommand cmd = new OleDbCommand(query, cn);
OleDbDataReader reader = cmd.ExecuteReader();
if (reader.HasRows)
{
while (reader.Read())
{
ptProductModel item = new ptProductModel
{
Number = reader[0].ToString(),
Name = reader[1].ToString(),
//comment = reader.GetString(reader.GetOrdinal("comments")) !=null ? reader.GetString(reader.GetOrdinal("comments")) : null,
price = reader[2].ToString()
};
listToReturn.Add(item);
}
reader.Close();
if (cn.State == ConnectionState.Open)
{
cn.Close();
}
toReturn = Json(listToReturn.Select(s => new { Name = s.Name, price = s.price, Number = s.Number }), JsonRequestBehavior.AllowGet);
}
}
catch (OleDbException ex)
{
toReturn = Json("Error", JsonRequestBehavior.AllowGet);
}
return toReturn;
}
}
And this is the angular controller:
myApp.controller('ptCatalogueController', ['$scope', '$http', function ($scope, $http) {
$scope.catalogueItems = [];
$scope.Product = "";
$scope.Init = function () { }
$scope.GetProducts = function (productSet) {
console.error(productSet, 'blabla');
$http.post({
url: '/Catalogue/GetCatalogueItems', data: { get: productSet }
}).then(
// success callback
function (data) {
$scope.catalogueItems = data;
console.log($scope.catalogueItems);
console.debug("success");
}
,
//error callback
function (response) {
console.log(response);
console.debug("error");
}
)}
}]);
and the header:
