Nuxtjs component not hotreloading on v-if condition change

Question

I have a navbar component that contains 2 buttons "Logout" and "Dashboard" that are rendered only if the user is authenticated. (using v-if).

However when the user click on the Logout button, the navbar is not reloaded and so the buttons stay visible until you reload the page. How do I set my v-if condition so that when the value of the v-if change, also the components (divs) update?

        <div class="buttons">
          <a v-if="userToken" class="button is-primary" style='padding:4px; margin-right:0;'>
            <b-button size="is-normal"
                type="is-primary"
                icon-right="close"
                outlined
                inverted
                style="margin-bottom: 0;"
                @click="logout">
                Logout
            </b-button>

          <a v-if="userToken" class="button is-primary" style='padding:4px; margin-left:0;'>

      let token = this.$cookies.get('userToken')
      if (token) {
        this.userToken = token
        this.$router.push('user_dashboard')
      }
    },
    logout() {
      this.$cookies.remove('userToken')
      this.userToken = ''
    }
  },
  mounted() {
    this.getUserToken()
  },
// ...

Ok I'm really sorry, I eventually solved the issue by making those changes:

methods: {
    getUserToken() {
      let token = this.$cookies.get('userToken')
      if (token) {
        this.userToken = token
        this.$router.push('user_dashboard')
      } else {
        this.userToken = ''
      }
    },
    logout() {
      this.$cookies.remove('userToken')
      this.getUserToken()
    }
  },
  mounted() {
    this.getUserToken()
  },
