In order for the WikiEditor toolbar to be extensible, we need a way to allow addition of toolbar buttons which execute custom functions when clicked. The 'callback' action seems to be created to address this issue. However, when you create a custom button with 'callback' action and pass the callback function name using the 'execute' property, this function is called when the toolbar is loaded (that is, right after the edit page is loaded).

Expected result would be not to execute the function on page load, but to only execute it when the specific button is clicked on.
