Detect changes in component checkbox (ng prime)

I have created a table with checkbox components (ng prime components). Does anyone know how I can control the event without changing the value? I have used the Onchange () function but was done before changing it so if my condition is successful the value is changed.

<p-checkbox [(ngModel)]="rowData[col.field]" binary="true" (onChange)="btnComprobarMismoTipo($event, rowData.etiqueta, rowData.tipo)" (change)="btnPrueba()"></p-checkbox>
