Setting State of ButtonTwoState

myToolbar.setItemState(id, state, callEvent);
The parameters for this method are the following:
- id - id of the two-state button;
- state - true/false, true stands for the Pressed state of the button, false stands for the Released state of the button;
- callEvent - if set to true, calls user defined handler for the onStateChange event (if there is any).
There is also the possibility to get current item's state by calling the getItemState method:
var isPressed = myToolbar.getItemState(id); // returns true/false
The method returns true in case the button is pressed, and false in case the button is released.
