Lack of support of DataTable with nested objects in datasource

[serralha85]

When using datatable

$('#gasTable').puidatatable({
paginator: {
rows: 50
}
, columns: [
{ field: 'name', headerText: 'Name', sortable: true, filter: true, filterMatchMode: 'contains' },
{ field: 'supplier.idSupplier', headerText: 'Name Supplier', sortable: true, filter: true, filterMatchMode: 'contains' }
]
, sortMode: 'multiple'
, selectionMode: 'single'
, draggableColumns: false
, responsive: true
, datasource: function (callback) {
$.ajax({
type: "GET",
url: '/GasStation/GetGasStations',
dataType: "json",
context: this,
success: function (response) {
callback.call(this, response);
}
});
}
});

Data source is
[
{"idGasStation":31,"name":"185540. TAVEL","supplier":{"idSupplier":828,"idClient":0,"code":"","name":"VelocityFleet","local":null,"zipCode":null,"address":null,"MORLOCALE":null,"CODPOSTALE":null,"MORADAE":null,"country":null,"fiscalNumber":null,"contact":null,"phone":null,"fax":null,"email":null,"obs":null,"idCompany":0,"tableName":"ComCfgFornecedores"}},
{"idGasStation":60,"name":"A GUDIÑA","supplier":{"idSupplier":225,"idClient":0,"code":"","name":"ADS - BADAJOZ DIESEL SERVICE SL","local":null,"zipCode":null,"address":null,"MORLOCALE":null,"CODPOSTALE":null,"MORADAE":null,"country":null,"fiscalNumber":null,"contact":null,"phone":null,"fax":null,"email":null,"obs":null,"idCompany":0,"tableName":"ComCfgFornecedores"}}
]

I want to access supplier.idSupplier and it doesn't support it?
