Using new schedule date as Title

Hi,
I have a need to use the DateTime of the new schedule on the schedule title, when I try to do it, I put the old Schedule DataTime on the new schedule title.

How can I do it?

Now I´m trying this:

schedulerData.push({
schedule_id: sch.ID(),
schedule_title: sch.DateStart().toString(),
event_id: sch.EventId(),
event_title: sch.Event().Title(),
text: text,
start_date: mibLightBlockProgramSchedule.SchedulerFormat(sch.DateStart().toString()),
end_date: mibLightBlockProgramSchedule.SchedulerFormat(sch.DateEnd().toString())
});

Hello,

Could you please clarify or show on the screenshot where you want to update new date?
Possible you need to use template to solve this requirement. More info about them you can find here:
