Escape key is not launching onClose() in reactkit Modal

[karendolan]

It is common behavior to use the [ESC] key as an alternative to using the mouse or tab to find the "X" close button on a popup. The [ESC] key is not executing the onClose() function in dce-reactkit.

Scenario:

• Launch a modal with an onClose() option
• Click the close X icon
• The onClose() executes
• Launch a modal wit an onClose() option
• Hit the [ESC] key
  ACTUAL: the onClose() is not executed
  EXPECTED: the onClose() is executed
