I really appreciate you being so willing to help, but I managed to get it working this morning.
I decided to firstly simplify the table and get it working with Jquery. You can try out the simple JSfiddle here, but basically it uses:
$(document).on("click", "#animals tbody tr", function() {
var animal = $(this).closest('tr').attr('id');
alert("I am a " + animal);
});
Once this was working, I adapted it to my Framework7 project:
$$('.data-table #airconList tbody tr').on('click', function (e) {
var zaf = $$(this).closest('tr').attr('id');
console.log(zaf);
})
