mixin.bind method

Links the specified action to the property specified in the name parameter. This function is invoked when the value of the property may have changed. It is not guaranteed that the action will be called only when a value has actually changed, nor is it guaranteed that the action will be called for every value change. The implementation of this function coalesces change notifications, such that multiple updates to a property value may result in only a single call to the specified action.

Warning  Do not attempt to bind data to the ID of an HTML element.
