How do I end activeFocus?

[Circuits]

I have a TextInput and I am looking for a way to end activeFocus s/t once a user presses enter on the Qt virtualKeyboard activeFocus falls off of the TextInput. I am trying to use the selectAll() method and this is working but not the way I need it to work, here is my code:

TextInput{
            id:inputItem
            text: "Enter text here"

            EnterKeyAction.enabled: inputItem.text.length > 0 || inputItem.inputMethodComposing
            EnterKeyAction.label: "Next"

            Keys.onReleased: {
                if (event.key === Qt.Key_Return) {
                    activeFocus = false
                }
            }

            onActiveFocusChanged: {
                if(activeFocus) {
                    selectAll()
                    inputPanelContainer.textDisplay = inputItem.text
                }
            }

            onDisplayTextChanged: {
                inputPanelContainer.textDisplay = text
            }
        }
    }

So, currently, the first time I click in the TextInput box the string is highlighted; however, the cursor just stays in the TextInput box even after I press enter. I want the focus to fall off of the TextInput each time the user enters their string s/t when they click the TextInput box again the string will highlight again, is this possible? Perhaps I am calling selectAll() in the wrong way or perhaps I am setting activeFocus incorrectly?
