Ui component checbox value is 0 with js element

This is my component field

    <field name="is_campaign_plp" formElement="checkbox">
        <argument name="data" xsi:type="array">
            <item name="config" xsi:type="array">
                <item name="component" xsi:type="string">Cpy_Cms/js/form/element/plp-campaign</item>
                <item name="source" xsi:type="string">plp</item>
                <item name="default" xsi:type="number">0</item>
            </item>
        </argument>
        <settings>
            <dataType>boolean</dataType>
            <label translate="true">Used for Campaign only</label>
            <dataScope>is_campaign_plp</dataScope>
        </settings>
        <formElements>
            <checkbox>
                <settings>
                    <valueMap>
                        <map name="false" xsi:type="number">0</map>
                        <map name="true" xsi:type="number">1</map>
                    </valueMap>
                    <prefer>toggle</prefer>
                </settings>
            </checkbox>
        </formElements>
    </field>

When I’m using <item name="component" xsi:type="string">Cpy_Cms/js/form/element/plp-campaign</item>
My checkbox systematically send the value 0 in the php form request.

var_dump($this->getRequest()->getParam(‘is_campaign_plp’)); //0 everytime

If I remove that js file…the data is properly sent.

var_dump($this->getRequest()->getParam(‘is_campaign_plp’)); //0 ou 1 depending on what i checked.

Inside my js…the value seems to be well recovered as the show hide is working fine.
