How do I access the values in the JSON model in my Dialogue list? - sapui5

Question

I have retrieved a JSON model from an ajax call in UI5 but I can't access its members. I have seen examples of people doing something similar but it isn't working for me. Here is my code:
onSumbmitFlowGAkQ: function () {
var oParameters = {
"value": this.getView().byId("flowInputGAK").getValue()
};
$.ajax({
url: "private url",
type: 'POST',
data: JSON.stringify(oParameters),
contentType: 'application/json',
success: function (data) {
this.getView().setModel(new JSONModel(data), "guidedAssistanceGAK");
this.setUpDialog();
}.bind(this),
error: function (e) {
MessageToast.show(e.status);
}
});
setUpDialog: function () {
var lst = new List({
items: {
path: "guidedAssistanceGAK>/flow",
template: new StandardListItem({
title: "{guidedAssistanceGAK>value}",
counter: "{guidedAssistanceGAK>ID}"
})
}
});
var dialog = new Dialog({
title: "choose one",
content: lst,
beginButton: new Button({
text: "OK",
press: function () {
dialog.close();
}
}),
afterClose: function () {
dialog.destroy();
}
});
dialog.open();
//this.oEditor.oRichTextEditor.setValue(this.getView().getModel("guidedAssistanceGAK").getProperty("/flow"));
},
I am using the syntax "guidedAssistanceGAK>/flow" to access the data but it isn't working. I think this is a binding error. I was wondering what would be the right way to do this.

The new dialog doesn't look to be part of the view, which is where your model lives. You could either do this.getView().addDependent(dialog), or you could attach the model to the dialog with dialog.setModel.
