Not getting data in Popover

I have a button in a table row. when I click that button popover opens, but the data is not shown.

this is what my code looks like for popover.

_handleLABEL: function(oEvent) {
    //1 open a popover and show labels
    var oCtx = oEvent.getSource().getBindingContext("poItem101SetJson");
    let oControl = oEvent.getSource();
    let oView = this.getView();

    // create popover
    if (!this._pPopover) {
        this._pPopover = Fragment.load({
            id: oView.getId(),
            name: "com.wel.goodsreceipt.fragments.popover.LabelPopOver",
            controller: this
        }).then(function(oPopover) {
            oView.addDependent(oPopover);
            oPopover.bindElement({
                path: oCtx.getPath(),
                model: "poItem101SetJson"
            });
            // oPopover.bindElement(oCtx.getPath(), { model: "poItem101SetJson"});
            oPopover.attachAfterOpen(function() {
                this.disablePointerEvents();
            }, this);

            oPopover.attachAfterClose(function() {
                this.enablePointerEvents();
            }, this);
            return oPopover;
        }.bind(this));
    }
    this._pPopover.then(function(oPopover) {
        oPopover.openBy(oControl);
    });
