updateCell funciton uses DOM API instead of jQuery API

[mohoch1]

The cellNode should not be treated as a DOM element as it is a jQuery object. The current code, is actually the code from the original SlickGrid, trying to set the HTML of the cell using innerHTML, while in the X-SlickGrid this element is actually a jQuery object.

The actual way to set the HTML in this element is using the jQuery.html() funciton

NOTE: There might be a need to review the entire flow and handle this in a lower level (maybe the getCellNode funciton), but this solves the critical issue.

Hi @mohoch1.

Could you add an example that demonstrates this bug?
