'ngModel', can't be found! even after defining ng-model in bootstrap-ui-datetime-picker

问题

Here is a codePen of the issue I am facing, CodePen.

Though the controller works fine and every logic runs fine, but I am not able to understand why I am getting the error in 'Chrome console error'

I am using angular js material https://material.angularjs.org/latest/ and for dateTime Picker I am using https://github.com/Gillardo/bootstrap-ui-datetime-picker Has anyone faced this?
