How to pass model to nested Marionette.CompositeView?

Question

backbone.js

There is a View which is used in CompositeView

var ItemView = Marionette.LayoutView.extend({
        tagName: 'tr',
        template: ItemTemplate,
        regions: {
            footer: "#content"
        },
        
        events: {
            'click td': 'showDismiss'
        },

          showDismiss: function () {
            var EmptyV = new DismissViewComposite();

            if (this.footer.hasView())
                this.footer.empty();
            else {
                <this.footer.show(EmptyV);

            }
            EmptyV.render();
        },

        templateHelpers: function () {
            var model = this.model;
            var numberFunc = this.numberFormatter;
            var dateFunc = this.dateFormatter;
         
            return {
                USER_NAME: model.get('USER_NAME'),
                TMC_TYPE_NAME: model.get('TMC_TYPE_NAME'),
                DISMISS_COUNT: model.get('D<code lang="javascript"></code>ISMISS_COUNT'),
                CULTURE_NAME:  model.get('CULTURE_NAME'),
                DATE: dateFunc(model.get('DATE')),
            };
        },

A region with a similar structure is nested in it, it is displayed on click.
It should also pick up data from the model, but this does not happen. The question is why?

var DismissViewComposite = Marionette.CompositeView.extend({
        childView: new DismissView(),
        childViewContainer: "tbody",
        className: 'historyItem',
        emptyView: EmptyView,
        template: DismissTable,

    });

    var DismissView = Marionette.ItemView.extend({
        tagName: 'tr',
        template: DismissItemTemplate,

        templateHelpers: function () {
            var model = this.model;
            var dismisses = model.get('VIEW_TMC_DISMISS_DATA');
            var numberFunc = this.numberFormatter;
            var dateFunc = this.dateFormatter;

            return {
                CLASS_TYPE: "1",
                COUNT_T:    1,
                ITEM_ID:   1
            };
        },

You need to explicitly pass the model.
var EmptyV = new DismissViewComposite({
model: this.model
});
