删除行后无法刷新 p-table 中的数据 (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 在某些情况下可能需要注意其值的变化，例如重新应用排序。出于性能考虑，仅当值的引用发生变化时才会这样做，这意味着使用 setter 而不是 ngDoCheck/IterableDiffers，这会降低性能。因此，当您操作值（例如删除或添加项目）时，不要使用 array 方法，例如 push，splice 使用展开运算符或类似方法创建新的数组引用。
