Button for bluetooth plugin from toggle event

I’m running an ionic app from example code from Don Coleman and am attempting to change the toggle button:

  <ion-toggle [(ngModel)]="power" (ionChange)="onPowerSwitchChange($event);"></ion-toggle>

into a regular button such as:

    <ion-item><button (click)="powerclickon()">ON</button></ion-item>
    <ion-item><button (click)="powerclickoff()">OFF</button></ion-item>

Eventually I would like to implement a touchstart touchend event for the button to cause it turn on when pushed and off when released.
