Check your file to make sure it is well-formed. ( https://validator.w3.org/ ) I have found that when the HTML has been edited to be invalid that the Interactivity pane may not correctly represent the bindings.
What framework are you using? For App Framework and jQuery Mobile, binding to a page is simply a matter of setting the href on a hyperlink and being sure to set the data-role="button". If I recall correctly. The respective docs should have it. For some of the other frameworks there will be an external script file (index_user_scripts.js) that is output that references an activate_page function. It varies by framework. Consult the docs of your framework.
