change config options in computed not work

I want to make date range with date-picker, so I have two date-picker in my template. I can see config change in vue-devtools, but it dose not work on date-picker. I still can pick any date without restrictions. Here's my code:

/*in template*/
<datePicker v-model="dateStart" :config="dateStartConfig"></datePicker>
<datePicker v-model="dateEnd" :config="dateEndConfig"></datePicker>

/*in script*/
data() {
    return {
        Start: new Date(),
        End: new Date(),
        dateStartConfig: {
            minDate: '2000-01-01',
            maxDate: new Date()
        },
        dateEndConfig: {
            minDate: '2000-01-01',
            maxDate: new Date()
        }
    }
},
computed: {
    dateStart: {
        get() {
            return this.Start
        },
        set(value) {
            this.Start = value
            this.dateEndConfig.minDate = moment(value).format('Y-M-D'))
        }
    },
    dateEnd: {
        get() {
            return this.End
            // return this.$store.state.order.dateEnd
        },
        set(value) {
            this.End = value
            this.dateStartConfig.maxDate = moment(value).format('Y-M-D')
        }
    }
}
