How to use ng-change in typescript1

Question

Please suggest me how to use ng-change in typescript1. Here I have some code

   <input type="text" ng-change="epc.fileChangeEvent()" />

typescript

fileChangeEvent():void {
         alert('file change');
        }

This is out of construction. Here I'm using kendo

Answer 1

change ng from ng-change

 <input type="text" (change)="fileChangeEvent()" >

in your component:

fileChangeEvent():void {
    alert('file change');
 };
