title: Chart.js: changing tooltip template
body: <p>I need to change Chart.js tooltip template, so that only value part is displayed in bold. There is tooltipTemplate option, which should do exactly this. Default value of this option is:</p>
  
  <pre><code>tooltipTemplate: "&lt;%if (label){%&gt;&lt;%=label%&gt;: &lt;%}%&gt;&lt;%= value %&gt;%"
  </code></pre>
  
  <p>I tried editing it like this:</p>
  
  <pre><code>tooltipTemplate: "&lt;%if (label){%&gt;&lt;%=label%&gt;: &lt;%}%&gt;&lt;strong&gt;&lt;%= value %&gt;&lt;/strong&gt;%"
  </code></pre>
  
  <p>But it displays <code>strong</code> tags on screen as part of text, instead of rendering bold text. I tried moving them around <code>&lt;%</code> and <code>%&gt;</code>, but it still doesn't work. Any ideas?</p>
