Your Actions builder looks slightly wrong to me. Here is a example I use:

public static void mouseClickByLocator( String locator ) {    
  WebElement el = driver.findElement( By.cssSelector( locator ) );    
  Actions builder = new Actions(driver);    
  builder.moveToElement( el ).click( el );    
  builder.perform();    
}
