Computed prop in VueJS not updated until input lost focus

same as title says. A computed property from a object it´s not reactive until the input box lost the focus.

But if the object is in data, the value changes as soon as changed in the input.

I created a codepen with the example: https://codepen.io/Albvadi/pen/QWwMOQV

<div id="container">
  <div class="row justify-content-center">
    <div class="col-md-8">
      <div class="card">
        <div class="card-header">Match Component</div>

        <div class="card-body">
          <div class="container">
            <div class="row align-items-center">
              <div class="col-4 text-right">{{homeTeam.desc}}</div>
              <div class="col-2">
                <input class="form-control text-center" type="number" min="0" v-model.number="homeTeam.score" />
              </div>
              <div class="col-2">
                <input class="form-control text-center" type="number" min="0" v-model.number="awayTeam.score" />
              </div>
              <div class="col-4">{{ awayTeam.desc }}</div>
              <div class="row">
                <div class="col">
                  DATA:
                  <b>{{ homeTeam.score }}</b>
                </div>
                <div class="row">
                  <div class="col">
                    COMPUTED:
                    <b>{{ awayTeam.score }}</b>
                  </div>
                </div>
              </div>
            </div>
          </div>
        </div>
      </div>
    </div>
  </div>
</div>

new Vue({
  el: "#container",
  data: {
    homeTeam: {
      name: "SPA",
      desc: "Spain",
      score: 0
    }
  },
  computed: {
    awayTeam: function() {
      return {
        name: "GER",
        desc: "Germany",
        score: 0
      };
    },
  },
  mounted() {
    console.log("Component mounted.");
  }
});

If you change the first input, the data value is changed inmediate. If you change the second input, the computed value if changed only when input lost focus.

How can I solve this?

== EDIT ==

Thanks for your answers! I know that putting awayteam in the data section solves the problem, it was just an example to simplify my problem.

My problem was that along with the two results, I wanted to have a computed property to be able to issue to another component. I edited the codepen with the final result: https://codepen.io/Albvadi/pen/jOELYwN and it´s working correctly.

But @Sami Kuhmonen comments that computed properties are only read properties but in my checkFinalResult I´m setting the computedMatch.. It´s the right approach??
