Data not yet available when running function

I have a styled countdown that is dependant on jquery. I load my end dates into input fields which I will eventually hide.

The function grabs the values here and starts up 3 instances of the countdown for my three cards that must display them

The input code looks like this:

onchange shows nothing, so I went with onupdated

In Wappler Design view it works and the countdown starts, but when testing in the browser no luck.

Help appreciated.

Everything is at the bottom before the footer

Two of the countdowns appear to be working fine here on Chrome / Windows 10.

I see it also works on my end on Opera, which is chromium. Seems to be a Safari problem. Then not sure if it is the jquery plugin or app connect…?
