In Nightwatch , How to call a command in test that exists in the "section"?

Question

I am using nightwatch to write my tests. In my page object i have "section". That section have commands but when I call the commands in the test, it returns "section is not a function". please find my page object and test below.

Page Object
sections:{
    Profile:{
        myprofile:'#myprofile',
        elements:{
            firstName:{
                selector:'//a [contains(text(),\'firstName\')]',
                locateStrategy:'xpath'
            }
        },
        commands:[{
            clickRedeem(){
                return this
                    .click('@myprofile')
            },
            clickMerchandise(){
                return this
                    .click('@firstName')
            }
        }]

    }
},

In test I am calling the command like this

 this.profileTest.section('@myprofile').clickProfile(); but its returning  
 this.profileTest.section is not a function  

I tried as you mentioned. please find the details below.

    redeemMenu:{
    selector:'#myprofile',
    elements:{
       merchandiseMenu:{
            selector:'//a [contains(text(),\'Merchandise\')]',
            locateStrategy:'xpath'
        },
    },
    commands:[{
        clickRedeem(){
            return this
                .waitForElementVisible('@redeemMenu')
                .click('@redeemMenu')
        },
        clickMerchandise(){
            return this
                .waitForElementVisible('@merchandiseMenu')
                .click('@merchandiseMenu')
        },


    }]

},



test

var profileSection = await this.profileTest.section.redeemMenu 
profileSection.clickRedeem()


Error: Element "redeemMenu" was not found in "redeemMenu". Available 
elements: merchandiseMenu

There are few errors:

1. You used wrong property and should change

   myprofile:'#myprofile'

   to

   selector: '#myprofile'

2. You used the wrong selector

   var profileSection = this.profileTest.section.redeemMenu

3. To use command :

    profileSection.clickRedeem()
