title: Input box appears, but nothing happens when you click
body: <p>I'm developing a web application using Angular 6. I'm using the bootstrap library <strong>bootsrap-select</strong> to create a custom input component that behaves like a  element (
  I needed the <em>live research</em>, for example).
  I entered the right dependencies in <strong>angular.json</strong>:</p>
  
  <pre><code>"scripts": [ 
                "./node_modules/path-to-files/bootstrap-select/js/bootstrap-select.js"
             ]
  </code></pre>
  
  <p>The problem is that if I insert simple code, like this:</p>
  
  <pre><code>&lt;select class="form-control selectpicker" data-width="250px" data-live-search="true" 
          title="Select the right value" data-size="10"&gt;
      &lt;option value="a"&gt;Value 1&lt;/option&gt;
      &lt;option value="b"&gt;Value 2&lt;/option&gt;
      &lt;option value="c"&gt;Value 3&lt;/option&gt;
  &lt;/select&gt;
  </code></pre>
  
  <p>The problem is that the input box appears, but nothing happens when you click on it!

  <p>How can I enable all features using Angular with TypeScript (without pure JavaScript )?
  Thanks for the help</p>
