On venue_submissions.js the first observableArray actually maps properly into the UI element. Programmatically pushing a new object adds the options into the select element. This doesn't happen with the second two observableArrays in either direction. This is reflected in the params that get posted: no tag information is to be found.

venue_submissions.js

this.viewModel.all_tags = ko.observableArray(options.allTags);
this.viewModel.search_options.selected_tags = ko.observableArray([])
this.viewModel.selected_tags = ko.observableArray([])
