Try putting in wait's in between your actions because Selenium doesn't know how angular loads and works. Protractor was created right for the purpose of handling angular web pages, which is a wrapper over selenium webdriver. However if you still want to test angularjs with Selenium then waiting for few seconds implicitly or fluent wait's between each action should help you with your need and accomplish what you intend to. Hope it helps.
