ListBoxValueChanged callback doesn't get called when I change value.

I want a specific function to get triggered, when I change the Value in a Listbox

my Code:

function DatenListBoxValueChanged(app, event)
            fill_table(app)
end

With the debugging functionality "Pause Excecution at Line XX" (==making the line number red) I found out that the Callback doesn't get triggered when I change the value.

How can I fix that?

(I have multiselect enabled if that's relevant)

Make sure that function is in fact the callback of the listbox:

1. In App Designer, Design View, select the listbox
2. In the Component Browser in the right side panel, click Callbacks and see what the ValueChangedFcn is

If the ValueChangedFcn is not DatenListBoxValueChanged, then enter or select DatenListBoxValueChanged in the ValueChangedFcn box.

Thank you for your answer!

But I don't think that's it. The callback should be correct

Design View:

Edit: I added the Design view

Closing MatLab (not just the App) and opening it again did the trick..
