Language Permalink / Custom Language Dropdown

Hello,

I created a custom Bootstrap language picker, because I did’t like the default dropdown and I couldn’t figure out how to place my SVG flag images. Only problem is that I cannot get the permalink working and stuck with a static one to the homepage?

<?php if (get_locale() == 'en_US') {?>
           						 
           						 <!--- EN -->
								 <?php // echo get_locale(); ?>
           						 <div class="langchooser btn-group">
                                                      <button class="btn btn-default btn-sm dropdown-toggle" type="button" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false">
                                                        <img src="<?php echo esc_url( get_template_directory_uri());?>/assets/img/english.svg" class="img-responsive" alt="English"> <span class="caret"></span>
                                                      </button>
                                          <ul class="dropdown-menu">
                                             <li><a href="<?php echo 'https://www.bla.com/nl' // dutch ?>">  <img src="<?php echo esc_url( get_template_directory_uri());?>/assets/img/dutch.svg" class="img-responsive" alt="Nederlands"></a></li>
                                          </ul>
                           		 </div>

<?php }else{ ?>
							            
							       <!--- NL -->
							          <?php // echo get_locale(); ?>
								  <div class="langchooser btn-group">
                                                      <button class="btn btn-default btn-sm dropdown-toggle" type="button" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false">
                                                        <img src="<?php echo esc_url( get_template_directory_uri());?>/assets/img/dutch.svg" class="img-responsive" alt="Nederlands"> <span class="caret"></span>
                                                      </button>
                                          <ul class="dropdown-menu">
                                             <li><a href="<?php echo 'https://www.bla.com/' // english ?>">  <img src="<?php echo esc_url( get_template_directory_uri());?>/assets/img/english.svg" class="img-responsive" alt="English"></a></li>
                                          </ul>
                           		 </div>        
                      
							            

		
 <?php } ?>
