Current behavior

<nz-input-number [(ngModel)]="demoValue" name="demoValue" [nzMin]="1" [nzMax]="10" [nzStep]="1"></nz-input-number>

会有两个问题：

• 若初始值 demoValue=1 时 “减” 的状态不正确。
• 文本框录入 1000 按下 Tab 键时依然是 1000

晚安！

I think _checkDisabled call the wrong location.

https://github.com/NG-ZORRO/ng-zorro-antd/blob/master/src/components/input-number/nz-input-number.component.ts#L168

export class NzInputNumberComponent implements ControlValueAccessor {
  // ...
  set nzValue(value: number) {
    if (this._value === value) {
      return;
    }
    if (value > this.nzMax) {
      this._value = this.nzMax;
      this.onChange(this.nzMax);
    } else if (value < this.nzMin) {
      this._value = this.nzMin;
      this.onChange(this.nzMin);
    } else {
      this._value = value;
      this._checkDisabled(); // disabled should be called after the setter function instead of here
    }
  }
}
