Ember handlebars How can I make an Ajax or jquery call for an handlebar file?

<div class="ui form segment">
    <div class="field">
      <div class="ui selection dropdown" tabindex="0">
        <div class="default text">
          Select
        </div>
        <i class="dropdown icon"></i><input name="hidden-field" type="hidden">
        <div class="menu" tabindex="-1">
          <div class="item" data-value="1">
            Choice 1
          </div>
          <div class="item" data-value="2">
            Choice 2
          </div>
        </div>
      </div>
    </div>
  </div>

this code is written inside a template.hbs(handlebar) file. I want to initialise the drop down with the following command

$('.ui.dropdown')
  .dropdown();

where could I write the second code? if it was an html/php file I could write inside the template
