TextProperty update when typing

[dipacs-ds]

There are some situations when I need the text in a text input while typing (on the fly search, etc...).
To prevent continuous property propagation with possible invalid values it can be a separated property with name like TextPreview or something else.

In the keyup event you can read the current (uncommitted) value of the textbox or textarea using the element.value field.

IMPORTANT: In the keyup event you don't get the last typed character, so you need to use a setTimeout(someFunction, 0);
