Ionic 2 - Keyboard Not Hiding on Form Input(text area). Issue present in iOS devices, android works fine

Question

When the user taps outside the input fields the keyboard is not hiding. Using ionic-plugin-keyboard on ionic 2. The UI template is as following,

<ion-content padding id="ten" no-bounce>
<div id="logo"></div>
<div id="infoText">{{ "PLEASEENTER" | translate}}<br>{{"name" | translate}}</div>
<div>
<form [formGroup] = "tn" id="tn">
<ion-item id="inputItem"  [ngClass] = "{'requiredField' : requiredFieldNotFilled}">
    <ion-textarea #input class="mediumFontInput" clearInput ="false"  type="text" name="name" formControlName="name" placeholder = "{{'NAME' | translate}}" [(ngModel)]="search" (input)="searchList($event)" (focus)="setCursorPosition($event)" ></ion-textarea>
</ion-item>
</form>
</div>
</ion-content>

Any help or suggestion is appreciated.
