    <!-- your content here -->
  </gridster-item>
</gridster>

Initialize the demo dashboard

###Events

Gridster Item

  @Output() itemChange: EventEmitter<GridsterItem> = new EventEmitter();
  @Output() itemResize: EventEmitter<GridsterItem> = new EventEmitter();
  ....
  this.itemChange.emit(this.state.item); // triggered when a item cols,rows, x ,y changed
  this.itemResize.emit(this.state.item); // triggered when a item width/height changed

Note: When a item changes cols/rows both events get triggered
