Eigenes Widget - Einträge duplizieren.

[Messa]

Hallo.

Ich habe mir ein eigenes Backend Widget gebaut / zusammenkopiert

Nun habe ich versucht aus dem ListWidget das Kopieren von Elementen nachzubauen, doch leider wird mit eifach nur die Seite neu geladet und das Input ist leer + das Select auf den ersten Wert gestellt.
Eventuell sieht jemand was ich falsch habe. Denke es lieg an der ID die übergeben wird.

In der Backend URL steht folgendes.
