What are you trying to do with that compute? This kind of thing might be a bug, but is a strange use case. You might be wanting to use the setter plugin and instead do:

can.Component.extend({
tag: "my-tag",
template: "<button>click</button> {{val}}",
scope : {
val: "default val"
setVal : function(newVal) {
alert('this function will never be called');
return 'I am the real value';
}
},
events : {
'button click' : function(el) {
this.scope.val(Math.random());
}
}
});
var template = can.view.mustache("<my-tag></my-tag>");
$("body").html(template());
