deleting a chip should trigger new search

[zemirco]

we have some paths like

fieldbus/profibus/a
fieldbus/profibus/b
fieldbus/profibus/c

• search for "fieldbus" and hit Enter -> chip appears and search is refreshed
• continue searching "profibus" and hit Enter -> another chip appears and search is refreshed
• now remove chip "profibus" -> I would expect the search results to auto refresh. However they stay the same and only after hitting enter the results refresh
