Hi,

Try this code to perform on click in odoo 16 form view.

var BasicRenderer = require('web.BasicRenderer');
var FormRenderer = BasicRenderer.extend({
            className: "o_legacy_form_view",
            events: _.extend({}, BasicRenderer.prototype.events, {
                'click .o_notification_box .oe_field_translate': '_onTranslate',
                'click .o_notification_box .btn-close': '_onTranslateNotificationClose',
                'shown.bs.tab a[data-bs-toggle="tab"]': '_onNotebookTabChanged',
                'click .o_form_label': '_onFieldLabelClicked',
            }),
            custom_events: _.extend({}, BasicRenderer.prototype.custom_events, {
                'navigation_move': '_onNavigationMove',
                'activate_next_widget': '_onActivateNextWidget',
                'quick_edit': '_onQuickEdit',
            }),
})
