在带有formControl的复选框中使用[value]设置ID，设置为true / false

Question

我需要将attribute.iditemAtribute的值传递给我的复选框，该属性分配给我的formControlName atributo_principal_id，但是，当我选中此复选框时，它在formControl中将其值设置为true，如何获得我的[value]的值？ / p>

我尝试过类似的事情：

//Print the value of my formcontrol, when i check the checkbox, the value printed is true/false, i need the id_atributo_principal in this formControl 
id item atributo: {{atributos.iditemAtributo}}
//Print of the id_item_atributo that i need in my formControl
id atributo: {{item.value.id_atributo_principal}}

<div class="custom-control custom-checkbox ml-2">
    <input formControlName="id_atributo_principal" [value]="atributos.iditemAtributo" type="checkbox" class="custom-control-input" id="atributo_principal{{indexatributo}}">
    <label class="custom-control-label" for="atributo_principal{{indexatributo}}">Atributo principal</label>
</div>
