How i can get the input value within ionic 2 in my Component as following?

ion-header> <ion-navbar primary> </ion-navbar> </ion-header> <ion-content> <ion-item> <button lightgray full (click)="incrementQty()">+</button> <ion-item> <ion-input type="number" min="1" [value]="qty" [(ngModel)]="qty"></ion-input> </ion-item> <button lightgray full (click)="decrementQty()">-</button> </ion-item> </ion-content>

import { Component} from '@angular/core'; import { NavController, Slides} from 'ionic-angular'; @Component({ templateUrl: 'build/pages/titlepage/titlepage.html', }) export class titlePage { qty:any; constructor(private nav: NavController) { this.qty = 1; } // increment product qty incrementQty() { console.log(this.qty+1); this.qty += 1; } // decrement product qty decrementQty() { if(this.qty-1 < 1 ){ this.qty = 1 console.log('1->'+this.qty); }else{ this.qty -= 1; console.log('2->'+this.qty); } } }

Both of the above

import { Component} from '@angular/core'; import { NavController, Slides} from 'ionic-angular'; @Component({ templateUrl: 'build/pages/titlepage/titlepage.html', }) export class titlePage { qty:any; constructor({private nav: NavController)} { this.qty = 1; } // increment product qty incrementQty() { console.log(this.qty+1); this.qty += 1; } // decrement product qty decrementQty() { if(this.qty-1 < 1 ){ this.qty = 1 console.log('1->'+this.qty); }else{ this.qty -= 1; console.log('2->'+this.qty); } }
