Missing code completion/code information after edit of .ui file

It looks like editing a .ui file in designer does not trigger and update of intellisense.

Steps to reproduce:

• Create new Qt widgets project
• Open the .ui file and add a pushbutton named pushButton
• in the project's cpp file (not main.cpp) try to use the newly added pushButton (ui.pushButton->)

Expected result:

• Code completion works and code using the new component is recognized by the editor. Compilation works

Actual result:

• No code completion. Wiggly red lines under parts that use the newly added component. Compilation works
