if statement in js.erb file based on param_name will_paginate (Ajax ca

I am trying to work out how to have multiple Ajax calls on the same page (same controller Action) using the will_paginate Gem. So far i have given each instance variable its own param_name so that they are not using the default param of :page

Example Controller

    @meats= Recipe.meat_recipes.paginate(:page => params[:meat_recipes], :per_page => 1)
    @vegrecipes = Recipe.veg_recipes.paginate(:page => params[:veg_recipes], :per_page => 1)
    @desserts = Recipe.dessert_recipes.paginate(:page => params[:dessert_recipes], :per_page => 1)

Then in the view

     <%= will_paginate @meats,  :param_name => 'meat_recipes'  %> (repeat this for individual instance variables)

So this part is fine. What i am doing is loading a partial when the AJAX request is made like so

.js.erb file

    $('#meatRecipes').html('<%= escape_javascript(render partial: 'meatrecipes') %>');
    $.setAjaxPagination();

so at the moment my meat instance variable is working fine. So how to conduct an if statement based on params?

I have tried this for example

    <% if @meats %>
    $('#meatRecipes').html('<%= escape_javascript(render partial: 'meatrecipes') %>');
    $.setAjaxPagination();
    <% end %>

    <% if @vegrecipes %>
    $('#vegRecipes').html('<%= escape_javascript(render partial: 'vegrecipes') %>');
    $.setAjaxPagination();
    <% end %>

Also tried

    <% if @meats[:param_name] == 'meat_recipes' %>
    $('#meatRecipes').html('<%= escape_javascript(render partial: 'meatrecipes') %>');
    $.setAjaxPagination();
    <% end %>

    <% if @vegrecipes[:param_name == 'veg_recipes' %>
    $('#vegRecipes').html('<%= escape_javascript(render partial: 'vegrecipes') %>');
    $.setAjaxPagination();
    <% end %>

but this doesn't work. So i guess my question is what do i use as my argument to ensure that the correct partial is being called for the particular pagination section.

Hope I have explained this correctly
