Current Behavior

Hi,

Currently using custom templates and everything works fine, however when I attempt to add a new array element via onAddClick, I see the flash of the item being added and then being immediately removed.

Reordering and delete buttons work fine so the formData is being dealt with correctly. It's just onAddClick that's a problem.

It's also odd that onChange is called 6 times when the button is clicked.

Expected Behavior

A new item should be added to the array and onChange called once.
