V-calendar: Input value for range is not updated for date picker

[maximzasorin]

Hello, I use date picker with ranges, when updating start of range calendar is updated, but input value is not. I created example for this: https://jsfiddle.net/maximzasorin/sknpqze5/, after clicking on the button, start of range is set to April 16, and calendar shows this, but input value does not change.

You need to reset the range object instead of just changing its child property.

update () {
  // this.range.start = new Date(2018, 03, 16);
  this.range = {
    start: new Date(2018, 3, 16),
    end: this.range.end,
  }
}

@nathanreyes Thank you, that's exactly what I did, but in first case I was confused that the calendar was updated and the input field is not, why it happens?
