How to use the bindings/register function in bindings

// Enable knockout 3.4 deferred updates.
    ko.options.deferUpdates = true;

    // Setup validation policy.
    ko.validation.init({
        errorMessageClass: 'val-msg',
        decorateInputElement: true,
        errorElementClass: 'invalid',
        errorsAsTitle: false,
        messagesOnModified: true,
        writeInputAttributes: true
    });

    // Register custom extenders, bindings, components and validation rules.
    registerExtenders(ko);
    registerBindings(ko);
    registerValidationRules(ko);
    registerComponents(ko, injectedServices);
