With these it helps Does the view model's assignment of this.pc.event have to be done in attached()? How about moving it to bind(), created() or the constructor?
view model
code :
bind() {
    this.pc.event = event_list.MY_EVENT;
}

Hope that helps Yo need to be sure that this.settings.bio_bg.url exist from the component birth, so compiler doesn't broke trying to render it. In order to do so, just setup a 'fake' url in the original data of the component:
code :
export default {
  data () {
    return {
      settings: {
        bio_bg: {
          url: '',
        }
      },
      bio: {}
    }
  },
  created () {
    this.$http.secured.get('/settings')
      .then(response => {
        this.settings = response.data
        console.log(this.settings)
      })
      .catch(error => this.setError(error))
  }
}
  data () {
    return {
      settings: {
        bio_bg: {
          url: 'http://via.placeholder.com/350x150',
        }
      },
      bio: {}
    }
  }

To fix the issue you can do The push() method ought to add purchase objects to the queue array, but as @FK82 pointed out in his comment, push() is adding multiple references to the same purchase object. This means that if you change the object by increasing the quantity, every purchase's quantity property will be updated.
You can give that a try here:
code :
const exampleComponent = Vue.component("example-component", {
  name: "exampleComponent",
  template: "#example-component",
  data() {
    return {
      queue: [],
      purchase: {
        product: null,
        customer: null,
        quantity: null
      }
    };
  },
  methods: {
    queuePurchase() {
      this.queue.push( this.purchase );
    }
  }
});

const page = new Vue({
  name: "page",
  el: ".page",
  components: {
    "example-component": exampleComponent
  }
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/vue/2.2.4/vue.min.js"></script>
<template id="example-component">
  <div>
    <p>The Queue has {{ this.queue.length }} items.</p>
    <input
      v-model="purchase.quantity"
      type="number"
      min="1"
      name="product"
      placeholder="Quantity"
    >
    <button @click="queuePurchase">
      Add to Queue
    </button>
    <pre>{{ JSON.stringify(this.queue, null, 2) }}</pre>
  </div>
</template>

<div class="page">
  <example-component></example-component>
</div>
const exampleComponent = Vue.component("example-component", {
  name: "exampleComponent",
  template: "#example-component",
  data() {
    return {
      queue: [],
      purchase: {
        product: null,
        customer: null,
        quantity: null
      }
    };
  },
  methods: {
    queuePurchase() {
      this.queue.push({...this.purchase});
    }
  }
});

const page = new Vue({
  name: "page",
  el: ".page",
  components: {
    "example-component": exampleComponent
  }
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/vue/2.2.4/vue.min.js"></script>
<template id="example-component">
  <div>
    <p>The Queue has {{ this.queue.length }} items.</p>
    <input
      v-model="purchase.quantity"
      type="number"
      min="1"
      name="product"
      placeholder="Quantity"
    >
    <button @click="queuePurchase">
      Add to Queue
    </button>
    <pre>{{ JSON.stringify(this.queue, null, 2) }}</pre>
  </div>
</template>

<div class="page">
  <example-component></example-component>
</div>

seems to work fine You need to assign all the properties with route.
Object.Assign makes a new COPY of the of the $route, including all enumerable OWN properties
code :
let obj = { ... this.$route.query }
this.$router.push({
   query: Object.assign({}, this.$route.query, obj),
});
element.ready vs angular.element($document).ready

Any of those help You don't need either.
ready isn't needed since element has to exist for link function to fire. Also there is no element level ready event ... it is only used at document level to account for full body of page existing. That stage is long over when angular is compiling directives.
