Triggering deletion of link + nodes without skipping events

GoJS
1

I have the following context menu objects:

var nodeMenu =  // right click context menu for each Node
    $(go.Adornment, "Vertical",
        {
            background: "#F5F5F5"
        },
        makeButton("Rediger",
            function (e, obj) { showDialog(obj.part.adornedPart) }),
        makeButton("Slett",
            function (e, obj) { myDiagram.remove(obj.part.adornedPart) })
    );

var linkMenu =  // right click context menu for each Link
    $(go.Adornment, "Vertical",
        {
            background: "#F5F5F5"
        },
        makeButton("Slett",
            function (e, obj) { myDiagram.remove(showDialog(obj.part.adornedPart)) })
    );

Firstly: the “remove”-call just removes the node from the diagram. What I need is for the node to trigger all the same events as selecting the node and pressing delete does. I have currently mapped deletion of nodes and links to my backend through the addModelChangedListener, but the .remove call doesn’t trigger this. How do I run a deletion that also triggers the same events as a delete keypress?

Secondly: When I run the remove call on the link, this just outright crashes. But when I have the correct method of handling node deletion maybe this will also fix this? If not, how do I trigger a deletion of links without skipping the deletion event? I tried using removeLinkData in place of .remove.

This is the makeButton function:

function makeButton(text, action, visiblePredicate) {
    return $("ContextMenuButton",
        $(go.TextBlock, { margin: new go.Margin(0, 50, 0, 5), text: text, font: "0.9375rem Verdana, sans-serif" }),
        { click: action },
        // don't bother with binding GraphObject.visible if there's no predicate
        visiblePredicate ? new go.Binding("visible", "", function(o, e) { return o.diagram ? visiblePredicate(o, e) : false; }).ofObject() : {});
}

Edit: From further testing, it seems the reason .remove doesn’t trigger the events is because it makes the change “outisde of a transaction”. So essentially I want a way to call it through a transaction, I suppose?

I found a method I could use: CommandHandler.deleteSelection.
