Callback when tags change, gets three arguments tags which is the new
tag array, changed which is an array of the tags that have changed and
changedIndexes which is an array of the indexes that have changed.
onChangeInput
Callback from the input box, gets one argument value which is the content of the input box.
(onChangeInput is only called if the input box is controlled, for this to happen both inputValue and onChangeInput need to be set)

inputValue
Similar to currentValue but needed for controlling the input box. (inputValue is only useful if you use it together with onChangeInput)
