Can not user command New-ADuser with new created attribute on AD Windows Server 2012

Please help me. I create the new attribute with the guide here: Youtube link: Add new Attribute in AD

I can edit the attribute that i created in "AD User and Computer" at "Attribute Editor" (Like the clip)

But, i can not create the new user with that attribute. The error below:

PS C:UsersAdministrator> New-ADUser bachhv2 -givenName Bach2 -employeeSex Male New-ADUser : A parameter caot be found that matches parameter name 'employeeSex'. At line:1 char:37 + New-ADUser bachhv2 -givenName Bach2 -employeeSex Male + ~~~~~~~~~~~~ + CategoryInfo : InvalidArgument: (:) [New-ADUser], ParameterBindingException + FullyQualifiedErrorId : NamedParameterNotFound,Microsoft.ActiveDirectory.Management.Commands.NewADUser

Please help me! I'm in stuck :(
