Day view template bugfix: Uncaught TypeError: Cannot call method 'getTime in TouchCalendarView.js:591

In short: datetime attribute was contained in not proper `<td>` - that cause an error `Uncaught TypeError: Cannot call method 'getTime' of undefined` on TouchCalendarView.js:591

So, the maing problem was in onTimeSlotTap: `var newDate = this.getCellDate(target);`. After this line value of newDate was undefined. `getCellDate` function look for the date in `datetime` attribute. But this attribute contains not in proper `td` tag.
