Dashboard with dynamic multi-select searchWhenChanged=false

[big_nuggets]

I have a multiselect input that gets populated by results from a search. When I set searchwhenchanged="false" it it doesn't add the selectedValue to the multiselect.

This is some broken code that I spaghettied together from searching, clearly I'm not great with Splunk:

require(['splunkjs/mvc', 'splunkjs/mvc/simplexml/ready!'], function (mvc) {

    console.log("multiselect_functions.js loaded.");

    function setupMultiInput(instance_id) {
        /*
         */

        // Get multiselect  
        //    var multi = mvc.Components.get(instance_id);

        // On change, check selection  
        //    multi.on("change", (selectedValues) => {
        //        console.log("values:  " + selectedValues);

        //    });

        var multi = mvc.Components.get(instance_id);

        // On change, check selection  
        multi.on("change", function() {
            console.log("change " +multi.val());
            multi.settings.set.choices("choices", ['53','57']);
            //blah
        });

    }

    var all_multi_selects = document.getElementsByClassName("input-multiselect");
    for (j = 0; j < all_multi_selects.length; j++) {
        setupMultiInput(all_multi_selects[j].id);
    }

});

 Above I'm just trying to insert to some random stuff, I get a multi.settings.set.choices is not a function error, so I am probably trying on the wrong object. Any help would be greatly appreciated it, thank you.

Doing this works:

multi.val(['AA','BB','CC']);
