Can't refresh data in p-table after deleting row ( PrimeNg )

Question

I m using primeng 8.1 with angular 8
I refer my p-table with #dt then i call dt.reset() and getcandidates() to refresh
But it shows first page of p-table without refreshing list i searched in official documentation but i don't find a solution so the only way to refresh data is to reload entire navigator page

<p-table #dt  
[paginator]="true"
[columns] = "cols"
[value]="listcandidats"
[totalRecords]="listcandidats.length"
[paginator]="true"
[rows]="5"
[style.top.px]="screenHeight/6"
>

<ng-template pTemplate="caption">
<div style="text-align: right">        
    <i class="fa fa-search" style="margin:4px 4px 0 0"></i>
    <input type="text" pInputText size="50" placeholder="Recherche multioption" 
(input)="dt.filterGlobal($event.target.value, 'contains')" style="width:auto">
</div>
</ng-template>
<ng-template pTemplate="header" let-columns>
    <tr>
    <th>Candidat</th>

   <th>Action</th>
    </tr>


</ng-template>
<ng-template  pTemplate="body" let-rowData >
    <tr [pSelectableRow]="rowData" >


      <td [style.width.px]="screenWidth/8"> <h3>{{rowData.nom}}</h3></td>


        <td>
     <button pButton type="button" label="modifier" (click)="showDialog(rowData.id)" class="ui- 
     button-rounded ui-button-warning">
    </button>

    <button pButton type="button" label="supprimer" 
    (click)="deletecandidat(rowData.id);dt.reset();getcandidats()" class="ui-button-rounded ui- 
    button-danger"></button>
        </td>

    </tr>
    <hr [style.width.px]="screenWidth">
   </ng-template>


   </p-table>

As per PrimeNg Document

Table may need to be aware of changes in its value in some cases such as reapplying sort. For the sake of performance, this is only done when the reference of the value changes meaning a setter is used instead of ngDoCheck/IterableDiffers which can reduce performance. So when you manipulate the value such as removing or adding an item, instead of using array methods such as push, splice create a new array reference using a spread operator or similar.
