React Hook Form reset Controller (value) to default - reactjs

Question

Here is an example of my component, wrapped into Controller
<div className="mt-1">
<Controller
control={control}
name="selectedBirthMonth"
defaultValue={selectedMonth}
render={({ field }) => (
< SelectBirthMonth
field={field}
startYear={startYear}
selectedYear={selectedYear}
months={months}
value={selectedMonth}
reducedMonths={reducedMonths}
onChange={useEffect(() => monthSelect(field.value)), [selectedMonth]}/>
)}
/>
</div>
For now I am just trying to reset it with a button. Later I'd love to conditionally reset, depending on the value in a sibling component. Would be great to get it work with the button in the first place:
<input
style={{ display: "block", marginTop: 20 }}
type="button"
onClick={() =>
reset(selectedBirthMonth)
}
value="Reset with values"
/>
I get en error: selectedBirthMonth is not defined. Bassicaly, what I am aming for,on click, the whole component goes to default / a state it had when first rendered. What am I missing?

Answer 1

reset didn't do the job somehow, but setValue did. However I am setting to a value, not to the original state after first render, but in my case it's same.
<input
style={{ display: "block", marginTop: 20 }}
type="button"
onClick={() =>
etValue('selectedBirthMonth', lastAvaliableMonth)
}
value="Reset with values"
/>
