Context passed but ignored - sapui5

Question

I'm creating an offline app.
When I create an item in a view, I'd like it to be printed in another view so I'm passing a context from a controller to another one thanks to the appView model :
controller where it comes from :
onCreateContainer: function () {
var oView = this.getView(),
containerNumber = oView.byId("addContainerNumberInput").getValue(),
containerWeight = oView.byId("addContainerWeightInput").getValue(),
C = this.getView().getBindingContext();
if (containerNumber !== "" && containerWeight !== "") {
var d = this.getModel("appView").getData();
if (!d["/LotSet('" + this.idParent + "')"]) {
d["/LotSet('" + this.idParent + "')"] = {};
}
d["/LotSet('" + this.idParent + "')"][C.getPath()] = C;
// this.getView().unbindObject();
this._navBack();
} else {
var emptyInputFields = this.getView().getModel("i18n").getResourceBundle().getText("emptyInputFields");
MessageToast.show(emptyInputFields);
return;
}
},
Then I get it back in the second controller :
var oTable = this.getView().byId("contenantsTable");
var appView = this.getModel("appView");
var oLot = appView.getData()["/LotSet('" + sObjectId + "')"];
for (var key in oLot) {
var I = new sap.m.ColumnListItem({
cells: [
sap.ui.xmlfragment(this.getView().getId(), "com.xxx.view.AjoutContenant", this)
]
});
I.setBindingContext(oLot[key]);
oTable.addItem(I);
}
The value of "oLot[key]" is good, it's the context I want to pass, unfortunately, it's completely ignored and the fragment prints elements from the initial context.
Any idea?

I think that the problem is that your are modifying the data of the model directly. The model doesn't know that you are doing it so it is not propagating the changes to the bond components. So you have to either modify the model using setProperty method, or you have to call updateBindings method after you are done modifying the data.
