next prev preferences won't work on ajax pagination

I changed the next and previous in dutch with volgend and vorige but when you click on the next page. It shows the default text and not my preferences

It also changes the colours of some titles when you click on a \\\\\\\'Lees meer...\\\\\\\' I expected it to show in the color (in this case green instead of blue)

We use the postgrid combo plugin
