Klar, kein Problem 
Im Endefekt mache ich es so, dass ich die Werte ĂĽber den inject alle paar Sekunden aus meinen globalen Variablen hole und dann in das Javascript object schreibe.
Ich hab das oben mal mit Vincent durchgekaspert, du kannst aber auch ĂĽberall das Object laden und deine Werte reinpacken und wieder speichern.
Ich fand es bei der vielahl von Werten so einfacher, und es birgt nicht die Gefahr, dass das Object an unterschiedlichen Punkten geöffnet und dann wieder gespeichert wird, das könnte dazu führen das eventuelle neue Werte überschrieben werden. Da müsste man penibel auf die Laufzeit achten, hierbei nicht. Dafür wird hier jedesmal “alles” geladen.
Naturlich nicht vergessen die Globalen Variablen auhc anzulegen, vermutlich hast du die Werte aber sowieso schon in solchen 
Viel spaĂź
