PrimeFaces SelectManyCheckbox - Uncheck all checkboxes using Javascript

Is there an easy way to select/deselect all checkboxes in a p:selectManyCheckbox using JavaScript?

I've got it working right now but my method seems overly complicated for something I feel should be simple from PrimeFaces

Code below:

The select boolean checkbox:

<p:selectManyCheckbox id="multiSelectPerformanceCb"
    widgetVar="multiSelectPerformanceCb"
    value="#{cc.attributes.filter.selectedCriteria}">
        <f:selectItems value="#{cc.attributes.filter.performanceCriteria}"
            var="criteria" itemLabel="#{criteria.text}"
            itemValue="#{criteria.description}" />
</p:selectManyCheckbox>

A method that is ran on a button click:

function performanceSliderBooleanClick()
    //Uncheck the inputs
    PF('multiSelectPerformanceCb').inputs.each(function(){
        this.checked = false;
    });

    //Remove ui-state-active from the outputs
    PF('multiSelectPerformanceCb').outputs.each(function(){
        $(this).removeClass('ui-state-active');
    });
}
