keyup введите несколько полей ввода

Question

Я определил два поля ввода, которые запускают свой собственный метод при нажатии клавиши ввода Enter:

<div class="row">
      <div class="col-md-12">
            <mat-form-field class="index-full-width col-md-11">
                    <input #autoCompleteContactInput
                            matInput
                            placeholder="Intervenant Interne"
                            aria-label="Intervenant Interne"
                            [matAutocomplete]="autoContact"
                            [formControl]="contactControl"
                            (keyup.enter)="getContacts($event)"
                       >
                       <mat-autocomplete (optionSelected)="selectContact()" #autoContact="matAutocomplete" [displayWith]="displayFnContact">
                          <mat-option *ngFor="let contact of filteredContacts | async" [value]="contact">
                             <span>{{ contact.nom }} - {{contact.prenom}}</span>
                          </mat-option>
                        </mat-autocomplete>
             </mat-form-field>
              <mat-progress-bar *ngIf="loadingcontact" mode="indeterminate"></mat-progress-bar>
     </div>
 </div>
 <br>
 <div class="row">
   <div class="col-md-12">
        <mat-form-field class="index-full-width col-md-11">
            <input #autoCompleteSiteInput
                   matInput
                   placeholder="Site"
                   aria-label="Site"
                   [matAutocomplete]="autoSite"
                   [formControl]="siteControl"
                  (keyup.enter)="getSites($event)"
          >
         <mat-autocomplete (optionSelected)="selectSite()" #autoSite="matAutocomplete" [displayWith]="displayFnSite">
               <mat-option *ngFor="let site of filteredSites | async" [value]="site">
                  <span>{{ site.libelle}}</span>
               </mat-option>
         </mat-autocomplete>
       </mat-form-field>
                            <mat-progress-bar *ngIf="loadingsite" mode="indeterminate"></mat-progress-bar>
  </div>
 </div>

• метод, вызываемый первым полем ввода, называется «getContacts ($ event)»

• метод, вызываемый вторым полем ввода, называется "getSites ($ event)"

Проблема в том, что getContacts всегда вызывается, когда я нажимаю Enter в поле ввода seond ...

Я не понимаю, почему, потому что атрибут "keyup enter" определен для каждого поля
