string resource is not working properly

I am trying to add Confirm Email field to Register form. Nop is not displaying proper title for that it shows
"Account.Fields.ConfirmEmail" as the title on Register form.


In RegisterModel.cs I have added the following field

        [NopResourceDisplayName("Account.Fields.ConfirmEmail")]
        [AllowHtml]
        public string ConfirmEmail { get; set; }

In Register.cshtml i have added the following block just below email

                    
                    <div class="inputs">
                        @Html.LabelFor(model => model.ConfirmEmail, new { }, ":")
                        @Html.EditorFor(model => model.ConfirmEmail)
                        @Html.RequiredHint()
                        @Html.ValidationMessageFor(model => model.ConfirmEmail)
                    </div>

In defaultResources.public.nopres i have added the code under Account-->Fields

                  <LocaleResource Name="ConfirmEmail">
                    <Value>Confirm email</Value>
                  </LocaleResource>

The files defaultResources.public.nopres.xml and defaultResources.admin.nopres.xml are only used during install. Adding new resources to these files will not affect an already installed site.

You can add new locale string resources to an installed site via Admin > Configuration > Languages > click 'View string resources' for your language > click the 'Add new record' button at the top of the grid > enter values for the 'Resource name' and 'Value' columns and click the 'Insert' button.

Note that Resource names must be unique -an error is displayed if you try to enter a duplicate. You can find existing resources to edit via the funnel icon in the 'Resource name' and 'Value' columns' header.
