[Vuejs]-Dynamic ion-select-options after receiving data from axios promise

If anybody wonder, I found solution.

<ion-item>
      <ion-label>Some label</ion-label>
      <ion-select placeholder="1" v-model="selectedOption" interface="popover">
        <ion-select-option v-for="(item, index) in tab" :key="index" 
           :value="item">{{item}}</ion-select-option>
      </ion-select>
</ion-item>

data() {
    return {
      tab: []
    },
created() {
    onClickFunction(){
       axios.post("http://some_php.php", formData)
        .then(res => {
            x = res.data[2]; 
            for (let i = 1; i <= res.data[2]; i++){
              this.tab.push(i);
            }
   }
}

This works as I expected.
