bug: React Hoof Forms/Ionic React: Fulfilling input value automatically based on input value tilting

# Bug Report

**Ionic version:**

[ ] **4.x**
[x] **5.5.2**

**Current behavior:**


It is imposible to handle both values when the current's input value is changing.

**Expected behavior:**

The current input must have a normal behavior while the other input's value changes as the current input's value change.

**Steps to reproduce:**

Just go to the input and change its value.

**Related code:**

With the following code it was working fine:
```tsx

Cash Amount


setValue(
"posValue",
calculateFieldValue(e.detail.value)
)
}
required
/>
{errors?.cashValue && (

)}



POS Amount


setValue(
"cashValue",
calculateFieldValue(e.detail.value)
)
}
required
/>
{errors?.posValue && (

)}




{packageDetails?.orderData?.currencySymbol}
{packagePrice}


Pay





```

It was working also with this other code:
```tsx
const [formChangeFieldName, setFormChangeFieldName] = useState<'cashAmount' | 'posAmount'>()
const formMethods = useForm();
const { register, watch, errors, handleSubmit } = formMethods;
const { cashAmount, posAmount } = watch()
---
const onChangeInput = (e: any & { target: { name: string } }) => setFormChangeFieldName(e.target.name)
---

---

```
This was working pretty fine, but after update **Ionic** to `5.5.2` it stopped to work: `onIonChange` is not triggered(ensured by log), avoiding to launch `setFormChangeFieldName(e.target.name)`.

So, We developed the next code:
```ts

Nakit
(
{
console.log("Firing onChange at Cash!")
setValue("posAmount", calculateFieldValue(e.detail.value!))
// onChange(e.detail.value!)
}}
onIonBlur={onBlur}
required
/>
)}
/>

{formErrorMessage(errors.cashAmount)}

Pos
(
{
console.log("Firing onChange at POS!")
setValue("cashAmount", calculateFieldValue(e.detail.value!))
// onChange(e.detail.value!)
}}
onIonBlur={onBlur}
required
/>
)}
/>

{formErrorMessage(errors.posAmount)}

Ödeme yap


{packageDetails.orderData.currencySymbol}
{packageDetails.orderData.price}



```

**Other information:**

We opened a [question](https://stackoverflow.com/questions/65440610/react-hook-forms-ionic-react-fulfilling-input-value-automatically-based-on-chan) on **StackOverflow** in order to get an answer about this concern.

**Ionic info:**

```

```

Start by reproducing the reported behavior in an Ionic React app using IonInput, React Hook Form, and Ionic 5.5.2, then inspect the IonInput onIonChange path and the provided controlled-input examples. Done means the change event fires when the input value changes and the paired field updates without breaking form validation.
