/**
* @brief OnApplyTemplate override. This function sets up the bindings between the textblock_, textbox_ controls and the Text property.
* @see https://msdn.microsoft.com/nl-nl/library/system.windows.frameworkelement.onapplytemplate(v=vs.110).aspx
* @remark If no adornerlayer can be found an error will be thrown which can be viewed in the logger. This will also stop the adorner and TextBox from being created meaning this control will be used like a normal textblcok control.
