Keyboard.close() is not working in Ionic2

Hi,
I’m trying to close a keyboard when user clear the search bar. This is what I’ve done so far

<ion-col style="padding:0px;" col-90 center>
				<ion-searchbar style="padding:0px;" (ionInput)="getItems($event)"  (ionClear)="onClear($event)"></ion-searchbar>
			</ion-col>

onClear(event){
    console.log('g');
    Keyboard.close();
  }

I’ve used ionic-native for keyboard API. As far as i think, it is supposed to close the keyboard as soon as i click cross button on search bar. The problem is it doesn’t do that! Am I missing something?

Do you see the “g” output in the console?

Yes I see it, the function runs fine but Keyboard.close() doesn’t close the keyboard

Can you try this code?

cordova.plugins.Keyboard.close();

Yes I tried that, I get error while building
