MathJax.Hub.Typeset() is the JavaScript command that can re-render the math content within your page or within individual elements that have been updated by current changes. If you are sure that all typesetting is finished, then you can call it directly, but in general it is good to use the safe way to call it, like this MathJax.Hub.Queue(["Typeset",MathJax.Hub]);

Read more instructions for how to use it here: http://docs.mathjax.org/en/v1.1-latest/typeset.html

For instance, MathJax.Hub.Queue(["Typeset",MathJax.Hub,"previewdiv"]); would re-render the updated contents of the HTML element with an ID of previewdiv after you have updated its contents using your jQuery call.
