Help me with this wordpress ajax problem, getting post content, not page content

[ReGGaeBOSS]

Hi,

I am trying to load pages using ajax but I am having some problems. Instead of the page content my posts are being loaded on page change.

Here comes my function and js:

	function my_ajax_pagination() {
	    $query_vars = json_decode( stripslashes( $_POST['query_vars'] ), true );

	    $query_vars['paged'] = $_POST['page'];


	    $posts = new WP_Query( $query_vars );
	    $GLOBALS['wp_query'] = $posts;

	    if( ! $posts->have_posts() ) { 
	        get_template_part( 'content', 'none' );
	    }
	    else {
	        while ( $posts->have_posts() ) { 
	            $posts->the_post();
	            get_template_part( 'content', 'page' );
	        }
	    }

	    die();
	}

JS:

(function($){

	function find_page_number( element ) {
		return parseInt( element.html() );
	}

	$(document).on( 'click', '.menu a', function( event ) {
		event.preventDefault();

		page = find_page_number( $(this).clone() );

		$.ajax({
			url: ajaxpagination.ajaxurl,
			type: 'post',
			data: {
				action: 'ajax_pagination',
				query_vars: ajaxpagination.query_vars,
				page: page
			},
			beforeSend: function() {
				$('main').empty();
				$(document).scrollTop();
				$('body').append( '<div class="page-content" id="loader">Loading New Posts...</div>' );
			},
			success: function( html ) {
				$('#loader').remove();
				$('main').append( html );
			}
		})
	})

})( jQuery );

Can anyone help me?
