backbone event for trigerring the method on parent view from the child view

We can trigger a fcuntiona on the parent view from the child view

For that we have to trigger a backbone event as follow in the child view:

     events: {
                'click [data-action="save-lookup"]': 'saveChanges'
            }, 

 saveChanges: function (e) {
                try {
                    e.preventDefault();
                    console.log("sruthy", e);
                    Backbone.Events.trigger('saveChanges:saved', { event: e });
                    } catch (error) {
                    console.error(error);
                }
            },

In the intialize of the parent view ,call save changes function when the event trigger as follow:

    //To call save changes function on save button click
                    Backbone.Events.on('saveChanges:saved', function (data) {
                        // Execute the function manually with the event parameter
                        this.saveChangesInventory(data.event);
                    }, this);
