title: Mathjax issue with MathJax.Hub.Queue and Typeset
body: <p>Following <a href="https://docs.mathjax.org/en/v2.5-latest/typeset.html" rel="nofollow noreferrer">this page</a>, I try to display a simple equation into a div container.</p>
  
  <p>Here is an example on <a href="https://jsfiddle.net/ysis81/v4zhLgmL/42/" rel="nofollow noreferrer">this jsfiddle link</a></p>
  
  <p>It seems that equation is not interpreted as a Mathjax equation and I don't know how to make it rendered.</p>
  
  <p><strong>JS :</strong></p>
  
  <pre><code>MathJax.Hub.Config(
  {
      messageStyle: "none",
      TeX: 
      { 
          equationNumbers: 
          {
              autoNumber: "all"
          } 
      },
      tex2jax: 
      {
          inlineMath: [['$','$'], ['\\(','\\)']], 
          displayMath: [ ['\\begin{displaymath}','\\end{displaymath}'], ['\\begin{equation}','\\end{equation}'] ],
          processEscapes: true,
          preview: "none"
      }
  });
  
  document.getElementById("containerCanvas").innerHTML = "$ax+b=c$";
  MathJax.Hub.Queue(["Typeset",MathJax.Hub,"containerCanvas"]);
  </code></pre>
