Thank you!

Remove the hidden attribute on the dialog element. Bootstrap has CSS that sets display: none on elements with that attribute, and it doesn't seem necessary anyway. Your browser's document inspector is a great tool for seeing things like that.

var themedialog = $("#theme-change-form").dialog({ autoOpen: false, height: 'auto', width: 450, modal: true, buttons: { "Update Theme": updateTheme, Cancel: function() { themedialog.dialog("close"); } }, close: function() { $('.subtheme-button').removeClass('active'); $('.subtheme-button.selected').addClass('active'); } }); //Open dialog when change logo link clicked $('#change-theme').on("click", function() { themedialog.dialog('open'); }); function updateTheme() { console.log('theme udated'); }

body { padding: 30px; }
