material ui - Datepicker persistent -

i use following code datepicker component:

<datepicker    hinttext="return on"    autook={true}    fullwidth={true}    onchange={(e, val) => this.setarrivaldate(val)} />

setarrivaldate method (action) in mobx store, sets

this.userinput.arrivaldate

to given val.

i have clear button in form, triggers action in store well, set

this.unserinput.arrivaldate = ''

using solution, displayed arrivaldate becomes persistant, since clear function of store triggers onchange event, automatically sets previous date.

any advice?
