Don't disable the Create Volume/Item button when building the data structure from the form.

If you have say, a <textbox> with on onchange event that disables a <button> and re-enables it shortly thereafter, and the onchange event was triggered by you clicking on said button while the textbox has focus/changes, then the disable action will prevent any click on the button from registering.
