Click outside to close not working

Hello, and thank you so much for making this awesome date time picker!

I looked through the code and "clickOutsideToClose" is set to true, but for some reason, even in the demos here https://logbon72.github.io/angular-material-datetimepicker/ when you click outside, the dialog doesn't close. Do you know why?

Only the mdcDateTimeDialog Service have the clickOutsideToClose set to true.
We should probably expose this attribute and clickOutsideToClose : default false.
As normal user click outside by accident.
