[Vuejs]-Vue v-for list not re-rendering after computed data update

First, try this change, just for sure, and let me know in comment it works or not.

export default {
  ...
  computed: {
    paginatedData() {
      ...
      const end = start + this.size - 1;
      ...
    },
  ...
};

And yes: instead of id, try to use index:

<div v-for="(poi, idx) in paginatedData" :key="idx">                
  <card :poi="poi"/>
</div>
