What can I do to replace a button in place of another in vuetify?

Question

I need replace a button when it's clicked because I need that button to have 3 states (entrada, salida and registrado),I already have those buttons but they only work when reloading the page, I just want it to render without reload, I add my code for a better explanation

vuetify-data-table

<td>
    <v-btn color="success" v-if="item.check_in == null && item.check_out == null"
        v-on:click="entrada(item)">
        Entrada</v-btn>
    <v-btn color="error" v-else-if="item.check_out == null && item.check_in !== null"
        v-on:click="salida(item)">
        Salida</v-btn>

    <v-btn v-else disabled>Registrado</v-btn>
</td>

You can play out with the buttons with in the <v-data-table> without any page refresh.

Live Demo :

new Vue({
  el: '#app',
  data () {
    return {
      headers: [
        {
          text: 'Check-In',
          value: 'checkin'
        },
        { text: 'Check-Out', value: 'checkout' },
        { text: 'Actions', value: 'action' }
      ],
      details: [
        {
          checkin: null,
          checkout: null,
          action: null
        },
        {
          checkin: 1,
          checkout: null,
          action: null
        },
        {
          checkin: 1,
          checkout: 3,
          action: null
        }
      ]
    }
  },
  methods: {
    entrada(index) {
      this.details.forEach((obj, i) => {
        if (i === index) {
          obj.checkin = 2
        }
      })
    },
    salida(index) {
      this.details.forEach((obj, i) => {
        if (i === index) {
          obj.checkin = null,
          obj.checkout = null  
        }
      })
    }
  }
})
