why this doesn´t work:
inputButton.addEventListener('onchange', jsFunction, false);
I change the inputbox and it doesn´t call jsFunction.

onchange is not fired when the value of an input is changed. It is only changed when the input's value is changed and then the input is blurred. What you'll need to do is capture the keypress event when fired in the given input. Then you'll test the value of the input against the value before it was keypressed.
That's why onchange is used with form controls, like input, select, checkbox, radio buttons, etc. The Javascript listens for user input and fires this event whenever a value gets updated.
The onchange attribute fires the moment when the value of the element is changed. Tip: This event is similar to the oninput event. The difference is that the oninput event occurs immediately after the value of an element has changed, while onchange occurs when the element loses focus.
Try change instead of onchange
inputButton.addEventListener('change', jsFunction, false);
