ajax error event?

[doodi-v1]

When you specify ajax:true, is there a way to also specify an error event? I've been unsuccessful finding this in the doc and I've tried adding the event to the bootgrid parameter directly and through the ajaxSettings to no avail. Example, in case my question is vague or incoherent:

$(mainGridID).bootgrid({
    ajax: true,
    ajaxSettings: {
        error: function(jqXHR,textStatus,errorThrown){
            if(jqXHR.status===400){
                document.location.reload();
            }else{
                console.log(jqXHR,textStatus,errorThrown);
                $(".notice").html("Error: "+errorThrown );
            }
        }
    },
    error: function(jqXHR,textStatus,errorThrown){
        if(jqXHR.status===400){
            document.location.reload();
        }else{
            console.log(jqXHR,textStatus,errorThrown);
            $(".notice").html("Error: "+errorThrown );
        }
    },...

Yeah. I can't find this in the docs either, and the docs say you can't override error.
