Signal emit Issue - Listview is not showing full list

[Mathan]

Hi,


I am binding an ListView with values passing from the cpp, Pls refer the code.

Issue: Listview displays only one row, mean first value, The rest of the rows are not appeared.

Checked:
I created an ListModel/ListElement in main.qml as test and bind with ListView, Now the Listview just working fine, display all values

I suspect after the signal emit, the error occurs.

Code snippet:

main.qml
----------

ListView {
        id: idListView
        anchors {
            left: parent.left
            leftMargin: 10 * scaleFactor
            right: parent.right
            rightMargin: 10 * scaleFactor
            top: rectangleToolBar.bottom
            topMargin: 10 * scaleFactor
            bottom: rectangleStatusBar.top
            bottomMargin: 10 * scaleFactor
        }
//        model: objHomeController.detailsModel // Display only one row
        //model: idListmodel                            //Working fine
        delegate: comsearchDelegate
        spacing: 10 * scaleFactor
        clip: true
 
        highlight:  Rectangle {
            color: 'grey'
            Text {
