the 'offset' parameter from 'pageSize' has a negative value when the 'params' parameter

Hi Amit Jain,

First I would like to thank you for all the great work on the plugin.

I have found some anomalous behavior with the pagination.

For the following code:
<g:render template="/user/list" model="[showButtons:true]"/>

And in _list.gsp

<util:remotePaginate controller="user" action="list" total="$

" update="user-list" pageSizes="[5, 10, 20, 50, 100]" params="[profile:showButtons]"/>

In version 0.2.5 when you selected one of the "pageSizes" options, nothing happened. ( without the field "params" it worked perfectly)

In version 0.2.6 when one of the "pageSizes" options is selected it changes the max field, but the "Next" button appears. I have seen that the field "offset" that is in the javascript has a negative value and it gets incremented by the specified amount but in negative (-10, -60, -110) when one of the "pageSize" values was selected.

Many thanks
