If there possibility to display element which depents on function’s result?
<div class="btn-group" if.bind="mySpecialFunction()">
<div class="btn-group" if.bind="myOtherFunctionReturnsArray().length !== 0">
I don’t want to use boolean property
I see that function is executed only once, when view is builded.
I would like to execute it everytime, to conditional display element.
