+// 2. Der state "dirty" soll eigentlich anzeigen, wenn ein Form-Field vom User geändert wurde; damit missbrauchst du es hier etwas
+// 3. Die Dirty-Variante: Pack in deine ngFor ein {{ onFirstLoad(data) }} rein, das einfach ausgeführt wird. müsstest dann natürlich abfangen, dass das nicht nach jedem view-cycle neu getriggert wird. Schön ist das nicht, aber besser als mit Timeouts^^
