It's javascript,

var lenderModel = this;

lenderModel.LenderId = ko.observable ();
lenderModel.FirstName = ko.observable ();
lenderModel.MiddleName = ko.observable ();
lenderModel.FirstLastName = ko.observable ();
lenderModel.SecondLastName = ko.observable ();
lenderModel.IdentificationCard = ko.observable ();
lenderModel.GenderId = ko.observable ();
lenderModel.GenderName = ko.observable ();
lenderModel.Email = ko.observable ();
lenderModel.IsActive = ko.observable ();
lenderModel.PhotoPath = ko.observable ();
lenderModel.CreateBy = ko.observable ();
lenderModel.CreationDate = ko.observable ();
lenderModel.ModifiedBy = ko.observable ();
lenderModel.ModifiedDate = ko.observable ();

}

lenderViewModel.Create = function () {
if (lenderViewModel.IsNew ()) {
$ .ajax ({
url: & # 39; / # / AdminLenders / Create & # 39;
data: ko.toJSON (lenderViewModel.LenderModel ()),
dataType: "json",
type: "POST",
contentType: "application / json; charset = utf-8",
async: true,
success: function (data) {
if (data.Success) {
LoadGenders ();
LoadListLenders ();
$ (# TextboxFirstName & # 39;). Val (& # 39;);
$ (# TextboxMiddleName & # 39;). Val (& # 39;);
$ (# TextboxFirstLastName & # 39;). Val (& # 39;);
$ (# TextboxSecondLastName & # 39;). Val (& # 39;);
$ (# TextboxIdentificationCard & # 39;). Val (& # 39;);
$ (# TextboxEmail #); Val (& # 39;);
$ (# ComboBoxGenders & # 39;). Val (& # 39;);
$ (# TextboxIsActive & # 39;). Prop (& # 39; verified & # 39; false);
swal ("lender created!", "you have successfully registered!", "successful")
}
if not {
swal ("Error creating lender!", data.Data, "error")
}
}
error: function (ex) {
alert (& # 39; occurring an error & # 39;);
}
});
}
};
