How can I have two separate search controls on one page?

I have an Omnibox that uses a TopFieldSuggestion item that redirects to a result page once the user has selected an item from the Omnibox valuelist. I also have a ResultsList that shows the latest articles and such. Both components call the .coveoForSitecore('init') method on the page, but it seems only the first component calling the init is loading.

**Update 2: init code samples (3 different search boxes/results lists on the same page)

1)

Coveo.$(function() {
    var options = @(Html.Raw(Model.GetJavaScriptInitializationOptions()));
    options["topFieldSuggestions"] = {
        omniboxSuggestionOptions: {
            onSelect: function (valueSelected, populateOmniBoxEventArgs) {
                window.location.href = "/guidelines#first=0&f:TopicSearchFacet=[" + valueSelected + "]";
            }
        }
    };
    Coveo.$('#guideSearchBox')
        .on("buildingQuery", function(e, args) {
            args.queryBuilder.advancedExpression.add('(' + '@(Html.Coveo().ToCoveoFieldName("contentitemtype"))' + '="Guidelines")')
        })
        .coveoForSitecore('init', options);
});

2)

Coveo.$(function() {
    if (!isOnSearchPage()) {
        var restEndpointUri = "/coveo/rest";
        Coveo.Rest.SearchEndpoint.endpoints.default = new Coveo.Rest.SearchEndpoint({
            restUri: restEndpointUri
        });
        Coveo.$('#mainSearchBox').coveo('initSearchBox', '/search');
    }
})

function isOnSearchPage() {
    return Coveo.$('#mainsearch').length > 0;
}

$(document).ready(function() {
    $('#searchDropdownBox').on("change", function() {
        var sval = $('#searchDropdownBox option:selected').val();
        if (sval != null && sval != "") {
            Coveo.$('#mainSearchBox').coveo('state', 'f:@(Html.Coveo().ToCoveoFieldName("ContentItemType"))', "[" + sval + "]");
        }
    });
});

3)

Coveo.$(function() {
    var options = @(Html.Raw(Model.GetJavaScriptInitializationOptions()));
    options.externalSources.push('ACC WordPress Blog');
    Coveo.$('#search-rfy').on("buildingQuery", function(e, args) {
        var exp = buildRFYQueryExpression();
        args.queryBuilder.advancedExpression.add(exp); 
        var ctIds = '("f53dd214-394c-402f-8fcb-928c795490ac","332172f7-e818-41a0-976e-9ab92513cae5")';
        args.queryBuilder.advancedExpression.add('(' + '@(Html.Coveo().ToCoveoFieldName("ClinicalTopicComputedIds"))' + '=' + ctIds + ')')
    })
    .on('afterInitialization', function(e){
        Coveo.$('.CoveoSort').eq(0).coveo('select'); // 0 index is 'relevancy'
    })
    .coveoForSitecore('init', options);
});
