ngModel (directive in module ng )

Is directive that tells Angular to do two-way data binding. It works together with input, select, textarea. You can easily write your own directives to use ngModel as well.

ngModel is responsible for:

• binding the view into the model, which other directives such as input, textarea or select require,
• providing validation behavior (i.e. required, number, email, url),
• keeping state of the control (valid/invalid, dirty/pristine, validation errors),
• setting related css class onto the element (ng-valid, ng-invalid, ng-dirty, ng-pristine),
• register the control with parent form.
