Searchbar isn't working proper

Ionic Framework ionic-v3
1

Hey!

I guess there is a bug with the searchbar at the latest Ionic version. First of all, after I checked in the documentation, I realized that the search function isn’t working there like before. But for my problem, I wanted to set the value of the searchbar programmatically, but I cant assign anymore for example this.selectZoneItem = "TEST". It was working in the previous version.

<ion-searchbar [(ngModel)]="zoneSearch" placeholder="Search for a zone..." [value]="selectZoneItem" 
        (ionInput)="filterZones($event)" 
        (ionClear)="onZoneCancel($event)">
</ion-searchbar>
