Call method when input text is changed

Question

I'm using Angular 5 with Materialize and I have a datepicker who works perfectly:

<input materialize="pickadate" 
 type="text" class="datepicker" placeholder="Selecione a Data" 
 [materializeParams]=datePickerParams>

I want to call a method like "dateChanged(date)" when this input date is changed, I've tried using (change)="dateChanged($event)" for instance, but isn't working.

Answer 1

use ngModel with ngModelChange

<input materialize="pickadate"  [ngModel]="date"
 (ngModelChange)="onKey($event)" type="text" class="datepicker" placeholder="Selecione a Data" [materializeParams]=datePickerParams>

Answer 2

I am not an angular expert too, I'm learning. If you use Reactive Form, you can use something like

this.form.get('date').valueChanges.subscribe(date => {
  // do what you want
  // Tue Apr 03 2018 00:00:00 GMT-0300 (Hora oficial do Brasil)
  // you can use date.getTime()
})

You just need to set formControlName in date input! I`d recommend to use reactive form! Can you try and tell me if its worked? Thanks and sorry for my knowlegde and english!
