[DMN Designer] Data Types - Shortcuts don't work after the a field is inserted by kebab menu

In the Data Types tab, the shortcuts don't work after the a field is inserted by the kebab menu.

Steps to reproduce:

• Create a DMN model
• Select Data Types tab
• Create a Structure Data Type
• Save the Data Type
• Add a nested Data Type by using the kebab menu
• Type a new name
• Press Ctrl + S

Actual result: the parent Data Type is saved (and the changes are lost)

Expected result: the child Data Type is saved and the changes are save.
