title: Select2 minimumInputLength Not Working After append()
body: <p>In my select2, I use minimumInputLength option to start filtering after a certain length.</p>
  
  <pre><code>selectExample.select2({
    minimumInputLength: 2
  });
  </code></pre>
  
  <p>But after dynamically append new option with append() function, this minimumInputLength option is not working.</p>
  
  <pre><code>selectExample.append('&lt;option value="10"&gt;Ten&lt;/option&gt;');
  </code></pre>
  
  <p>What happened exactly? Is there a specific way to append new option for select2?</p>
  
  <p>The current solution I use is redeclaring the .select2() with the minimumInputLength option included.</p>
