You can use computed properties for this. Make one that depends on both
properties and then add a change listener.

computed: {
  state: "[first, last]",
}

+        this.update_();
+      },
+
+      lastChanged: function() {
+        this.update_();
+      },
+
+      update_: function() {

stateChanged: function() {

+        this.data = model.commitDataListForRevisionRange(this.first, this.last);
+      },
+    });
+  </script>
