我无法使用sapui5中的对话框显示表中选定行的数据

<script src="https://openui5.hana.ondemand.com/resources/sap-ui-core.js" id="sap-ui-bootstrap" data-sap-ui-libs="sap.m"></script>

<Table id="myTable" items="{/data}">
    <columns>
        <Column>
            <Text text="Name" />
        </Column>
        <Column>
            <Text text="Age" />
        </Column>
    </columns>
    <items>
        <ColumnListItem press="onItemPress">
            <cells>
                <Text text="{Name}" />
                <Text text="{Age}" />
            </cells>
        </ColumnListItem>
    </items>
</Table>

onItemPress: function(oEvent) {
    var oSelectedItem = oEvent.getSource();
    var oContext = oSelectedItem.getBindingContext();
    var sPath = oContext.getPath();
    var oModel = this.getView().getModel();
    var oSelectedData = oModel.getProperty(sPath);

    // 创建对话框并设置内容
    var oDialog = new sap.m.Dialog({
        title: "Selected Data",
        content: new sap.m.Text({
            text: "Name: " + oSelectedData.Name + "\nAge: " + oSelectedData.Age
        }),
        beginButton: new sap.m.Button({
            text: "Close",
            press: function() {
                oDialog.close();
            }
        })
    });

    // 打开对话框
    oDialog.open();
}
