Issue with lining up buttons and texts

I am having issue with lining up buttons & texts in the Ionic2. Below is my code:

<ion-content padding class="cart">
	<ion-row *ngFor="#item of items; #position=index">
		<ion-col width-50>{{item.barcode}}</ion-col>
		<ion-col width-20><input type="number" placeholder="Qty" [(ngModel)]="item.qty" style="width: 50px;" /></ion-col>
		<ion-col><button clear danger small (click)="remove(position, item)">Remove</button></ion-col>

In frontend, the button does not line up with the Text and QTY input. ANyone knows how to fix this?
