Dropdown Not working inside a repeater

Hi Wix Team,

I have a dropdown and a repeater. I have an on change event connected to that dropdown. But If i move that dropdown inside the repeater, and trigger the onchange event the the value of dropdown is printed as undefined.
If i move out of the repeater, it is printing the evalue properly. Why is this like this. Any new bug ? Or I am doing it wrong?
