You can also override and extend nothing and just create a controller action like so:

Ext.define('MyApp.controller.MyForm', {
    extend: 'Ext.app.Controller',

    markMandatoryFields: function(field, options) {
        if (field && field.isFieldLabelable && field.fieldLabel && field.allowBlank == false) {
            field.fieldLabel += ' *';
        }
    },

    init: function() {
        this.control({
            "field": {
                beforerender: this.markMandatoryFields
            }
        });
    }
});
