Facing issue in set date in rangedate-picker

[mvtdev1050]

I'm trying to set a default date in vue-rangedate-picker but it's not showing in input. Follow is my code:-

<vue-rangedate-picker v-model="effected_date" @selected="onDateSelected2" i18n="EN" format="YYYY-MM-DD">

and model initialize:-

data: function () { return { effected_date: { start: '2018-10-18', end: '2018-10-20', } } }

But it's not worked. Then I have searched solution and got this:-

<vue-rangedate-picker :initRange="datePickerConfig.initRange" @selected="onDateSelected" i18n="EN" format="YYYY-MM-DD">

data: function () {
return {
datePickerConfig:{
initRange: {
start: new Date('2018-10-15'),
end: new Date('2018-10-21')
}
}
}
}

Still it's not worked for me. Please help me to get solution for set default date.

Thankyou
