How to Trigger Knockout-Computables manually ...
There really does not seem to be a native method for this in the current version being 3.1.0.
Alternatively just expand knockout with this extended computable:
/**
* add a computed to knockout,
* that can manually trigger an value update with forceUpdateNotification()
*/
ko.forcibleComputed = function(readFunc, context, options) {
var trigger = ko.observable().extend({notify:'always'});
var target = ko.computed(function() {
trigger();
return readFunc.call(context);
},
null,
options
);
target.forceUpdateNotification = function() {
trigger.valueHasMutated();
};
return target;
};
