I loop a child components that has emitted data and pass to local data in parent but my expectation result is not what i get. It should be in incremental like this. Example

Index       Total
0             5
1             7
2             10
3             12

here my code:

<template>
  <div>
    <div v-for="data, index in myArr">
      <child-block-1
        :key="index"
        :data="data"
        @emittedData="total += $event"
      />
      <child-block-2 v-if="total > 10" />
    </div>
  </div>
</template>

The total data will add the emitted data, but when i check the total it will always the overall total 12. not the incremental.

Is there any other solution for this to get what my expected result ?
