Issue description

I have a simple form that contains a text box, drop down, checkbox and text area.
For all the controls I am using the standard HTML controls except the checkbox where I am using an ng-checkbox. If I use the standard input type="checkbox" then the formatting is not coming out properly. To make the formatting work I am using the ng-checkbox.

Current behavior:
When I populate the form and set the ngModel values, all the controls dirty and touched are false except the ng-checkbox. If I change the ng-checkbox to input type=checkbox and try the same thing the dirty and touched are coming out as false.

I am using ngx-admin and nebular.
