I'm trying to upload a file only if the user clicks on 'Yes', it is not calling the method but

new to ionic so I'm not sure if this is right way to call a method in Alert.

 async presentAlertConfirm() {
  const alert = await this.alertController.create({
    header: 'Upload Documents',
    subHeader: 'Do you want to Upload Documents?',
    mode: 'ios',
    backdropDismiss: false,
    buttons: [
      {
        text: 'NO',
        role: 'cancel',
        cssClass: 'secondary',
        handler: (blah) => {
          console.log('Confirm Cancel: blah');
          
        }
      }, {
        text: 'YES',
        handler: () => {
          console.log('Confirm Yes, yipe')
        // this.changeListener
          this.addImageLan;
          // const el: HTMLElement = document.getElementById('test');
          // el.click();
        }
      }
    ]
  });
  await alert.present();
}

Any help will be useful
