Solution

  • jQuery get() is for retrieving the underlying DOM element from the jQuery object. It accepts an integer index instead of a string. Try this.ui.tbody.get(0).childElementCount or this.ui.tbody.get(0).getAttribute('childElementCount')

    or withjQuery:

    this.ui.tbody.prop('childElementCount') or this.ui.tbody.children().length
