Input fields reset


I need to give the users the chance to clear the data they entered in ion-select and ion-datetime.
Is there a way to un-select options and reset selected date from the user interface?
Thank you

I created my form using form builder this way:

myField1: [],
myField2: []


      <ion-label>My Label 1</ion-label>
      <ion-select  [formControl]="myForm.controls['myField1']">
        <ion-option value="value1">Value 1</ion-option>
        <ion-option value="value2">Value 2</ion-option>
        <ion-option value="value3">Value 3</ion-option>

<ion-item >
      <ion-label>My Label 2</ion-label>
      <ion-datetime displayFormat="DD/MMM/YYYY"  [formControl]="myForm.controls['myField2']" [max]="maxDate"  >
