Show/hide custom button dynamically from section schema

Hi team,

I want to show/hide a custom button depending on a field of an opportunity, in the page what I do is to create an attribute with dependencies to this field to call the method that points to the property of the diff  (visible/enabled), but in the section I can't do this. I would like to know how I can make the same thing of the example below in the section.

The attribute I made in the page: 

"SubastaValidate": {
               dependencies: [{
                   columns: ["Stage"],
                   methodName: "ShowButton"
               }]
           },

In the diff of the page add the property:

"enabled": {
                        "bindTo": "ShowButton"
                    },

Thanks in advance,

Nicolas
