To load the clientlibs files via a page property dialog

I have created a custom experience fragment template type and using that template type have created an experience fragment template also. Both of this template refers to a node which has a dialog to add the certain JS & CSS in the XF. This node has a property- checked whose value is true by default but despite of that, files are not loading. 
When i go to the page properties and simply do the save & close, it gets loaded. 

When checked in the crx/de, i found that in the master.html node, the property is not getting generated itself. 

The requirement is to load the property by default when the property is checked without manually saving it. I need the solution for the same without using the sling model.
