Hi Derek,

when you use clearValue() it doesn't trigger the onChange script

try removing newValue === '' in the function

function onChange(control, oldValue, newValue, isLoading, isTemplate) {
if (isLoading || newValue === '') {
return;
}

change this to below

function onChange(control, oldValue, newValue, isLoading, isTemplate) {
if (isLoading) {
return;
}

Mark Correct if this solves your issue and also mark Helpful if you find my response worthy based on the impact.
Thanks
Ankur
