The v-if condition does not work

[miladfa7]

i use vue currency Input for input formatted numbers.
I created two files vuejs 3 :

CurrencyInput.vue

<template>
  <input  class="form-control form-control-solid" ref="inputRef" type="text" :value="formattedValue" />
</template>

<script>
import { useCurrencyInput } from "vue-currency-input";
import { watch } from 'vue'

export default {
  name: "CurrencyInput",
  components:{
    
  },
  props: {
    modelValue: Number,
    options: Object,
  },
  setup(props) {
    const {  inputRef, formattedValue, setOptions, setValue } = useCurrencyInput(props.options);
    watch(
      () => props.modelValue,
      (value) => {
        // Vue 2: props.value
        setValue(value)
      }
    )
    watch(
      () => props.options,
      (options) => {
        setOptions(options)
      }
    )
    return { inputRef, formattedValue };
  },
};
</script>

I wrote this part briefly
Project.vue

<template>
       <botton @click="showPrice()">add</botton>
       <div v-if="show==true">
        <CurrencyInput v-model.lazy="project.price" :options=options />
        </div>
</template>

<script>
  import CurrencyInput from "./CurrencyInput.vue";

export default {
  name: "project",
  components:{
    CurrencyInput
  },
  setup() {
   
   const showPrice = async () => {
       show = true
   
}

</script>

The problem is that when clicked on add the if condition does not work and is not displayed (CurrencyInput v-model.lazy="project.price" :options=options )

notice: when I use input instead CurrencyInput in Project.vue, the code works correctly.

I used this CurrencyInput in two components that are in the same path, I think I should stop or async watcher?
Do you think i can use async in watcher?

Your issue is not clear. Can you provide a minimal reproduction, for example a CodeSandbox?
