computed factory - Dynamically generate computed properties

Any suggestion how to create/improve a computed factory function used to dynamically create computed getters and setter ?

I have a solutions witch is not perfect need to pass the emit to make it work.

export default function computedFactory(field, value, emit) {
    return {
        get() {
            return value;
        },
        set(newValue: string) {
            emit(`update:${field}`, newValue);
        },
    };
}
