Did you press sync in de B4J IDE? BANano does use the info in the .b4j file to build the .dependsOn file. (For this reason you can also not have folders in your assets files as the B4J IDE does not support that).
It is not the functionality of the BANanoDependsOnAsset() method to ADD files. The BANano Transpiler can use these directives and ONLY add them to your FINAL Web App IF you do use a SKDatePicker in your Web App! So if you do not use them, those Assets will not be loaded, hence making your final Web App a lot lighter.
