what is ngmodel in angular code example

Example 1: what is ngmodel property binding

<input [(ngModel)]="username">

<p>Hello {{username}}!</p>

Example 2: ngmodel div angular 7

NgModel expects the bound element to have a value property, which div s don't have. That's why you get the No value accessor error. I don't know if the input event is supported on all browsers for contenteditable . You could always bind to some keyboard event instead.
