Hello, trying to make a copy in the list. 
The buttons pass the correct index, the index I pass through this.$root.$emit('copy', this.index)
Parents picks up and executes copy and made increment & decrement by the same principle
methods: { copy (index) { this.list.push(this.list[index]) }, increment (index) { this.list[index].score >= 10 ? false : this.list[index].score++ }, decrement (index) { this.list[index].score <= 1 ? false : this.list[index].score-- } }, But of some hell all the values are the same.
