JS Controller:

		var cmpTarget = component.find('Modalbox');
		var cmpBack = component.find('Modalbackdrop');
		$A.util.removeClass(cmpBack,'slds-backdrop--open');
		$A.util.removeClass(cmpTarget, 'slds-fade-in-open'); 
    	},
	openmodal:function(component,event,helper) {
		var cmpTarget = component.find('Modalbox');
		var cmpBack = component.find('Modalbackdrop');
		$A.util.addClass(cmpTarget, 'slds-fade-in-open');
		$A.util.addClass(cmpBack, 'slds-backdrop--open'); 
	},
    saveMentor: function(component, event, helper) {
        var mntr = component.get("v.newMentor");
        var action = component.get("c.CreateMentor");
        action.setParams({ 
            "mntr": mntr
        });
        action.setCallback(this, function(a) {
            var state = a.getState();
            if (state === "SUCCESS") {
               // var name = a.getReturnValue();
                document.getElementById("backGroundSectionId").style.display = "none";
                document.getElementById("newMentorSectionId").style.display = "none";
            }else if (a.getState() === "ERROR") {
                $A.log("Errors", a.getError());
            }
        });
        $A.enqueueAction(action)
    },
})

Apex Class:

public class createMentor {
    @AuraEnabled
    public static void CreateMentor(Mentor__c mntr){
        insert mntr;
    }
}

Thanks
