I'm having trouble making Can Deactivate work in my application. In the file form.component.html I have the following code:

   <div class="form-group">

    <label for="quoteType">Quote Type</label>

    <select class="form-control" id="quoteType" name="QuoteType" #type (change)="getQuoteType(type.value)">

      <option selected="selected">---</option>

      <option value="New">New</option>

      <option value="Amendment">Amendment</option>

      <option value="Migration">Migration</option>

      <option value="Replacement/Renewal">Replacement/Renewal</option>

    </select>

  </div>



  <div [ngSwitch]="quotetype">

    <div *ngSwitchCase="'New'">

      <app-form-new [quotetype]="quotetype"></app-form-new>

    </div>

    <div *ngSwitchCase="'Amendment'">

      <app-form-amendment [quotetype]="quotetype"></app-form-amendment>

    </div>

    <div *ngSwitchCase="'Migration'">

      <app-form-migration [quotetype]="quotetype"></app-form-migration>

    </div>

    <div *ngSwitchCase="'Replacement/Renewal'">

      <app-form-replacement-renewal [quotetype]="quotetype"></app-form-replacement-renewal>

    </div>

  </div>

Depending on what I select will render a different component in this template. In this case I will select "New"!

After New is selected:

What I want is: if the user starts filling out the form and unwittingly or purposely hit the back button to the previous page, a message appears asking if he really wants to do this.

I can do it on other pages of this system, but when I go to those forms it does not work. Below is the code I have made so far.

new-can-deactivate-guard.service.ts



import { Injectable } from '@angular/core'

import { CanDeactivate } from "@angular/router";

import { FormNewComponent } from './form-new.component'



@Injectable({

    providedIn: 'root'

})

export class FormNewCanDeactivateGuard implements CanDeactivate<FormNewComponent> {

    canDeactivate(component: FormNewComponent): boolean {

        if(component.formNew.dirty) {

            return confirm('Are you sure you want to discard your changes?')

        }



        return true

    }

}

Routing file:

export const ROUTES: Routes = [



    { path: '', component: TelaAcessoComponent },



    { path: 'homepage', component: HomepageComponent, children: [

        { path: '', component: QuotesAbertasComponent},

        { path: 'quotes-abertas', component: QuotesAbertasComponent},

        { path: 'quotes-fechadas', component: QuotesFechadasComponent},

        { path: 'quotes-qss', component: QuotesQssComponent},

    ] },



    { 

        path: 'quotes-abertas/:id', 

        component: QuotesAbertasDetalhesComponent,

        canDeactivate: [QuotesAbertasCanDeactivateGuard]

    },



    { 

        path: 'quotes-fechadas/:id', 

        component: QuotesFechadasDetalhesComponent,

        canDeactivate: [QuotesFechadasCanDeactivateGuard]

    },



    {

        path: 'quotes-qss/:id', 

        component: QuotesQssDetailsComponent,

        canDeactivate: [QuotesQssCanDeactivateGuard]

    },



    { path: 'formulario', component: FormularioComponent },



    { 

        path: 'formulario-New', 

        component: FormNewComponent, 

        canDeactivate: [FormNewCanDeactivateGuard]

    },



    { path: 'formulario-Amendment', component: FormAmendmentComponent },

    { path: 'formulario-Migration', component: FormMigrationComponent },

    { path: 'formulario-Renewal/Replacement', component: FormReplacementRenewalComponent },

    { 

        path: 'products/:id', 

        component: ProductsComponent,

        canDeactivate: [ProductsCanDeactivateGuard]

    },
