The Angular 2 "Trim" directive can be used to update the ngModel by simply adding it to the input element that has the ngModel attribute. Here's an example:

<input type="text" [(ngModel)]="myValue" trim>

In this example, the "trim" attribute has been added to the input element. This tells Angular to apply the "Trim" directive to the input. When the user types into the input, any whitespace at the beginning or end of the input value will be trimmed off. The trimmed value will then be updated in the ngModel variable "myValue".

Note: the "Trim" directive needs to be imported into your component, either in your component file or in a shared module.
