The Text element is trying to access a model field that lies within the path /d/results within your JSON model. You cannot reach this relative path directly without reference to the /d/results path. In your view if you are using some container control within you display the Label and Text controls then try binding the container to the path /d/results in the controller like below:
//assuming that the container has an ID "cont1"
sap.ui.getCore().byId("cont1").bindElement("/d/results");
Now the Text control will be able to resolve the relative path (relative to /d/results) that you have bound it with.
