我有一个在primeNG数据表之外的刷新按钮.如何以编程方式触发刷新数据表？

这样的事情:

<div class="pull-right">
  <button
    id="FilterBtnId"
    (click)="???">
  </button>
                </div>
<p-dataTable
   #datatable
   [value]="datasource"
   [(selection)]="jobs"
   [totalRecords]="totalRecords"
   selectionMode="multiple"
   resizableColumns="true"
   [pageLinks]="10"
   [rows]="10"
   [rowsPerPageOptions]="[10, 25, 50, 100]"
   [paginator]="true"
   [responsive]="true"
   [lazy]="true"
   (onLazyLoad)="getNewDatasource($event)"
   (onRowSelect)="onRowSelect($event)"
   >
     <p-column [style]="{'width':'40px'}" selectionMode="multiple"></p-column>
     <p-column *ngFor="let col of dt.colDefs" [field]="col.field" [header]="col.headerName" [sortable]="true">
     </p-column>
</p-dataTable>
