How to change the value of a string in a component?

Question

Vue.js

The parent component renders the child component:

newString(v-for='(item, index) in stringslist.' 
                :key='item.id' 
                :info='item' 
                @delete-string="deleteString(index)"

The values ​​are taken from the stringslist array. In the array, the objects with the value name.

child component

.example__wrapper
            .example__name(v-if="!changeName") {{info.name}}
            .example__name_change(v-else)
            ul.example__actions
                li.example__edit edit
                li.example__delete(@click="removeCell") delete

changeName: false

How to add change method to child component if array is created in parent component.
Received and added the value to the array in the parent, and now you need to change it in the child and pass it back to the parent array.
I figured out the removal, but I can't change the value.

PUG, my God, it's good that I dumped him, what a horror, how do you live with him? -_-
down (parent->child) props are slid,
up (child>parent) events
so add change event

newString(v-for='(item, index) in stringslist.' 
                :key='item.id' 
                :info='item' 
                @delete-string="deleteString(index)"
                @change="onChange(index, $event)"

and let the child send a data change event to the top, and change it in the parent, then they will update themselves
