EditTemplate not working with two way data binding in version ^17.3.27

I'm building an app where the user edits data in a grid. For each column I specify a editTemplate with either a dropdown, numeric textbox, textbox or multiselect to edit the value for the given column. For the controls in the editTemplate I use two way data binding. Recently I build a prototype of this app to see what is possible with the grid and this worked just fine. This week I started building the actual app, but this method seems to fail with the version of the grid. The controls in the editTemplate are shown, but when I save a added record, the record is empty. The controls in de editTemplate doesnt seem to modify the data at all. The version where this method does work is ^17.2.51 and the version where it doesnt work is ^17.3.27. To illustrate the problem I made a test component:

<ejs-grid #grid [dataSource]="data" [toolbar]="toolbar">
        <e-column field="number" headerText="Nummer">
            <ng-template #editTemplate let-data>
                <ejs-textbox [(value)]="data.number"></ejs-textbox>
        <e-column field="name" headerText="Naam">
            <ng-template #editTemplate let-data>
                <ejs-textbox [(value)]="data.name"></ejs-textbox>

import { ComponentViewChild } from '@angular/core';
import { GridComponent } from '@syncfusion/ej2-angular-grids';

  selector: 'app-test',
  templateUrl: './test.component.html',
  styleUrls: ['./test.component.css']
export class TestComponent {

  constructor() { }
  @ViewChild('grid', { static: false }) gridGridComponent;  
  dataany[] = [{number: 1name: 'Test'}];
  toolbarstring[] = ['Add''Edit''Delete''Update''Cancel'];

  ngAfterViewInit() {
    this.grid.allowKeyboard = false;
    this.grid.editSettings.allowEditing = true;
    this.grid.editSettings.allowAdding = true;
    this.grid.editSettings.allowDeleting = true;
    this.grid.editSettings.mode = 'Normal';
    this.grid.enableHover = false;

Hi Jochim, 
Greetings from Syncfusion. 
You can achieve your requirement by using the below way. Please refer to the below code example. Documentation link and sample link for more information. 
    selector: 'app-root', 
    template: `<ejs-grid #grid [dataSource]="data" [toolbar]="toolbar" (actionBegin)="actionBegin($event)"> 
        <e-column field="number1" isPrimaryKey='true' headerText="Nummer"></e-column> 
        <e-column field="number2" headerText="Nummer"> 
            <ng-template #editTemplate let-data> 
                <ejs-textbox [(ngModel)]="orderData.number2"></ejs-textbox> 
        <e-column field="name" headerText="Naam"> 
            <ng-template #editTemplate let-data> 
                <ejs-textbox [(ngModel)]="orderData.name"></ejs-textbox> 
export class AppComponent { 
   .  .  . 
  actionBegin(args: SaveEventArgs) { 
        if (args.requestType === 'beginEdit' || args.requestType === 'add') { 
            this.orderData = Object.assign({}, args.rowData); 
        if (args.requestType === 'save') { 
            // cast string to integer value. 
            args.data['number2'] = this.orderData['number2']; 
              args.data['name'] = this.orderData['name']; 
Please get back to us if you need any further assistance on this.
