title: protractor- button click is not responding
body: <p>I have a button on a page that looks like: </p>
  
  <pre><code>button type="submit" name="username" value="123wq"
         class="user-option__action"&gt;test1&lt;/button&gt;
  &lt;span class="user-option__description"&gt;TM&lt;/span&gt;
  </code></pre>
  
  <p>I tried following code:</p>
  
  <pre><code>element(by.buttonText("test1")).click();
  browser.actions().mouseMove(btntest1).click();
  element(by.css('button[value="1"]')).click();
  element(by.buttonText('test1')).click();
  
  element.all(by.id('test1')).get(0).click();
  element( by.css( '.select option[value="test1"]' ) ).click();
  element(by.css('.test1')).click();
  
  //selenium.click(NEXT_BUTTON_XPATH)
  element(by.xpath('//input[@value='123wq'][@title='test1’]')).click();
  </code></pre>
