title: add a space between two templated variables, angularjs
body: <p>I have the following div. I am trying to add a space between two templated variables, but the single quotes keep showing up on the screen:</p>
  
  <pre><code>&lt;b class="stylefont" ng-click="ctrl.display(1)"&gt;
     {{ctrl.car}} + ' ' + {{ctrl.car2}}
  &lt;/b&gt;
  </code></pre>
