KendoNumericTextbox not updating when value set

I am having trouble updating kendoNumericTextBox when I update the val it will not show until I put my cursor into the textbox.

 $(document).ready(function () {
 
 $('#txtCorpEl').kendoNumericTextBox({}).data("kendoNumericTextBox");
 
 $('#txtCorpEl').value(5);
 
 $('#txtCorpEl').focus();
 
 //var numerictextbox = $("#txtCorpEl").data("kendoNumericTextBox");
//numerictextbox.focus();
 
 });
 
 
 function onChange() {
    console.log("event: change");
};

This is working fine when I test it.
