Repeater on QT Calendar displays incorrectly when month changed - qt

Question

I am working with the QtQuick controls calendar,
Within this calendar each date is highlighted if the corresponding date is within my database (stored as JSON) - Until now if there is multiple dates within the database, they are displayed only using a single marker (which has worked fine) (noted in the code eg). I am now looking to add a repeater to show multiple highlights, if the date exists more than once in my database.
The repeater is working (code below), but only on the month the calendar is opened in -when you change the visible month in the calendar the repeater either shows the markers on dates from the initial month the calendar was opened in, or not at all?
the code below is an example of my calendar, and below that some of the JSON (I have placed at the bottom for a working example)

A sample of my JSON used as calendarListModel is (extreamly long, but so you can have a full example of changing dates):

Answer 1

I have got this working by changing my Repeater {model: {…}} code too;
model: {
var found = calendarListModel.filter(
function (element) {
return element.date === styleData.date.getTime();
}
);
if(found === undefined)
return 0;
return found.length;
// this was changed from directly assigning the repeater.model as
// return repeater.model = found.length
}
