(ngModelChange) does not fire when I remove all values or paste values

Question

The (ngModelChange) event does not fire when I clear all values from input field by using Ctrl.A or paste a value into it.

<input pInputText (ngModelChange)="IsElementDataMissingForMultiValue(languages.TranslationValue)"  
    [(ngModel)]="languages.TranslationValue" type="text" />

function Controller()
{
    function IsElementDataMissingForMultiValue(value)
    {
        alert(value)
    }
}

The (ngModelChange) event triggers when I remove values one by one or add values one by one. But it does not trigger when removing all values by using Ctrl+A or pasting values by using Ctrl+V.

Did you check all required polyfills are installed? https://angular.io/guide/browser-support Have you tried in Chrome, Firefox? — Günter Zöchbauer, Jul 13 '17 at 12:20
But I have tested in IE 11 and IE edge. it's does not working @GünterZöchbauer — Ramesh Rajendran, Jul 13 '17 at 12:21
Might be a bug that only occurs in IE/Edge. Before you create a bug report ensure the required polyfills are installed. — Günter Zöchbauer, Jul 13 '17 at 12:22

It's my mistake.

The problem occurred when I does not assign $event to ngModel object in some event's

This below code does not working

(ngModelChange)="IsElementDataMissingForMultiValue(languages.TranslationValue)"

But the below code working like a charm!.

(ngModelChange)="languages.TranslationValue = $event; 
IsElementDataMissingForMultiValue(languages.TranslationValue)"

I hope this may be helps others.

I guess what you actually should have changed is `(ngModelChange)="IsElementDataMissingForMultiValue($event)"` – Günter Zöchbauer Jul 13 '17 at 14:32
