Having problem to place navigation with load plugin page

Hello

I am having a problem to place the navigation with a plugin page. My case is as below;

I have one master page where I am filtering the content as per user type and the data is loaded to the master page from a child page and I placed the filtered result to the master page by using framework_load_plugin_url with Ajax which is present to your tools.

Now the problem comes, when there are lot of results coming and in order to control not to load all the results I need to put a page navigation to the child page like per page 20 results should load at a time.

Normally the filtering everything is working OK but when I click to the navigation link to go to next page then it is not staying in the master page as new page link is creating on url and it is pointing to another page and everything become a mass.

I need your guide where and how to put the navigation so that I does not generate any url or it navigate inside the master page. Note that I am filtering the content base on POST variable.
