Vue rerender component on reset button

Question

I have a reset button which reset the state to the initial values. I need to rerender the component with currentTab is there any bet way to do it?

<button @click="resetData">reset</button>

<keep-alive>
    <component :is="currentTab"></component>
</keep-alive>

methods: 
resetData() {
    this.$store.dispatch('resetData')
    // re-render component based on the currentTab
    ??
}

currentTab I'm getting from the list of tabs:

tabs: [One, Two, Three]

There are a few ways to force a render. To do so from the parent, set a key on the child. Changing the key will cause the child to rerender:

HTML:

<component :is="currentTab" :key="tabKey"></component>

In the parent, define the key as a number:

data() {
  return {
    tabKey: 0
  }
}

Change the key:

methods: {
  resetData() {
    this.tabKey++;
  }
}

Note: Using this.$forceUpdate from within the component will only cause its view to rerender.
