Object type is not displayed with custom template

[Sergei Koba]

Hello,

I am trying to use custom template for my form. Here is the code of html:

<script type="text/template" id="template">

    <form enctype="multipart/form-data">

        <div data-fields="address"></div>

    </form>

    </script>

here is js:

$(function() {

    var User = Backbone.Model.extend({

        schema: {

           address: { type: 'Object', subSchema: {

        street: {},

        zip: { type: 'Number' }

    }}

        }

    });

    

    var user = new User({

    });

    

    var form = new Backbone.Form({

        model: user,

        template: _.template($('#template').html()),

    }).render();

    

    $('body').append(form.el);

});

I can see only the heading "Address" no editting fields. When I use in template "data-fieldsets" I see everything but I need to show fields seperately.
