FolderListModel refresh list problem

[RiteshPanchal]

I am using ListView using FolderListModel in Qt 5.2.1 on Ubuntu

Rectangle {
            id: listRect
            width: rootWindow.width
            height: rootWindow.height
            color: "transparent"
            visible: false

            Column {
                Rectangle {
                    width: listRect.width
                    height: 35
                    color: "transparent"
                    Text {
                        id: imgStr
                        text: qsTr("");
                        color: "white"
                        font.pixelSize: 20
                        anchors.verticalCenter: parent.verticalCenter
                        x: 20
                    }
                }

                Rectangle {
                    id: iHeader
                    width: listRect.width
                    height: 50
                    color: "blue"
                    Text {
                        id: tep
                        text: qsTr("Image Viewer");
                        color: "white"
                        font.pixelSize: 24
                        font.bold: true
                        anchors.centerIn: iHeader
                    }
                }

                Rectangle {
                    width: listRect.width
                    height: 20
                    color: "black"
                }

                Rectangle {
                    width: rootWindow.width
                    height: listRect.height - 105
                    color: "black"

                    FolderListModel {
                        id: imageModel
                        folder: "file:///media/ubuntu/exSATA/QtVideoBoxDATA/Images"
                        sortField: "Time"
                        sortReversed: true
                    }

                    Component {
                        id: fileDelegate
                        Rectangle {
                            width: imageList.width
                            height: 20
                            color: "transparent"
                            Text {
                                x: 10
                                text: fileName
                                color: "white"
                                font.pixelSize: 16
                                anchors.verticalCenter: parent.verticalCenter
                            }
                        }
                    }

                    Component {
                        id: imageHighlight
                        Rectangle {
                            width: imageList.width
                            height: 20
                            color: "green"
                        }
                    }

                    ListView {
                        id: imageList
                        width: rootWindow.width
                        height: listRect.height - 105
                        spacing: 10
                        currentIndex: currentIndex

                        model: imageModel
                        delegate: fileDelegate
                        highlight: imageHighlight
                    }
                }
            }
        }

My program is adding files to the folder used by FolderListModel. But when i review the ListView after, the last file name in list shows the same as the first file name. But when i try to read property of that file name it shows right name. But the list view shows the wrong name.
If i restart the application it shows the right list.

I display list using following at key event.

listRect.visible = true
imageList.focus = true
