        var action = cmp.get("c.france");    
         
        action.setParams({ NicoPinFrance : firstName });

         action.setCallback(this, function(response) {
            var state = response.getState();
             
            if ( state === "SUCCESS") {

                var errors = response.getError();
                if (errors) {
                    if (errors[0] && errors[0].message) {
                        console.log("Error message: " + 
                                 errors[0].message);
                    }
                } else {
                    console.log("Unknown error");
                }
            }
        });

        $A.enqueueAction(action);
    }
})

I want to set wrapper values to the UI: input how can  do it
component.set("v.partnumber", PartNicomat);
component.set("v.PartDescription",PartDescription);
component.set("v.PartStock",PartStock)

Thanks in advance
