the datetime picker cannot update when user modifying value

[wqdjl]

when i input value 2017-09-05 and reopen the datepicker ,the date picker still show the last value ;
eg.

I have the solution,
Please update datetime-picker.directive.ts' function ngOnChanges. when user modifying value ,you should be call setInputElDateValue、updateDatepicker
eg.

 if (!this.userModifyingValue) {
          setTimeout(() => {
            let dt = this.getDate(date);
            dt.toString = () => NguiDatetime.formatDate(dt, this.dateFormat, this.dateOnly);
            this.ngModel = dt;
            this.inputEl.value = '' + dt;
          })
  } else {
          this.setInputElDateValue(date);
          this.updateDatepicker();
 }

A good idea, I think. Please test and make a PR.
Please also consider that user may enter invalid date. 2017-0x-xx

you can valid the value ,
let date: any = new Date(value);
if (date == "Invalid Date")

• Go to datetime-picker.directive.js file and find below code (in i have this on line 273 check yours.) component.defaultValue = _this.defaultValue || _this.el['dateValue'];
• simple change the assigned values to _this.el['dateValue'] || _this.defaultValue ;
  it worked for me perfectly because i was using the default-value.
  also similar change in ts file i.e datetime-picker.directive.ts
• find component.defaultValue = this.defaultValue || this.el['dateValue'];
• change sequence component.defaultValue = this.el['dateValue'] || this.defaultValue;

in Above fix we prefer the Element value rather then default value .. i.e if value is change by user then popup 'll display from user provided value Otherwise/else default value.
Thanks @wqdjl for hint......
