Single quote in title breaks Page/TextTags field inside repeater

[Laksone]

I think i found a bug in Page/TextTags field if used inside of a repeater and with default ajax loading enabled if one of the selectable pages contains a single quote ( ' ).

It's not possible to add or expand repeater items and a JS error is shown:
Uncaught SyntaxError: unexpected token: string literal

Steps to reproduce:

• Add template (for example "event")
• Add a page with that template and a title containing a single quote ( ' )
• Create a Page/TextTags field ("event" template as selectable pages)
• Create a repeater field, add the TextTags field and add it to whatever template
• Create a page and try to add a new repeater item

This only happens if ajax loading of repeater items is enabled.
