Reac Hook Form - Submit button only activates when I press tab or click off inputs

Question

Even by entering the password it only activates the send button when I click out of the input or tab. Why is this happening? How can I correct?

const {register, handleSubmit, formState:{errors, isValid} } = useForm({mode:"all",});

<input 
  {...register("password", {
    required: "Insira sua senha",
  })}                        
  type="password"
  id="password"
  name="password" 
  placeholder="*********" 
  value={password}
  onChange={text => setPassword(text.target.value)}
/> 
<button
  disabled={!isValid}
  type="submit">
  Enviar
</button>
