Props are read-only, and you are trying to mutate yours with v-model. Thus if you change the input value, the prop is not modified and the value is restored on the next update.

Use a data property or a computed setter instead:

computed: {
  propModel: {
    get () { return this.prop },
    set (value) { this.$emit('update:prop', value) },
  },
},
