And this code snipped taken form PRS 600 kbook.so let me hope that this can be done.

	this.Fskin.kbookKeyboard.keyboard.addLetter = function (obj, text, code) {
		var event, words, container, wlen, strExisted, candidate, idx;
		if (this.field) {
			event = new <global>.Event(2048);
			if (!code) {
				code = text.charCodeAt(0);
			}
			if (this.numberOnly) {
				words = this.field.getValue();
				if (words && words == '0') {
					if (code == 48) {
						return;
					}
					if (48 + 1 <= code && code <= 48 + 9) {
						event.key = '';
						event.keyCode = 8;
						this.field.keyDown(event);
					}
				}
			}
			event.key = text;
			event.keyCode = code;
			this.field.keyDown(event);
			container = this.container;
			if ('sandbox' in container && 'updatePageNo' in container.sandbox) {
				container.sandbox.updatePageNo();
			}
			words = this.field.getValue();
			if (this.numberOnly) {
				wlen = (words)?words.length:0;
				strExisted = (wlen > 0)?true:false;
				this.updateBtn(strExisted, this.strModified, false);
			}
			else {
				candidate = this.candidate;
				if (candidate) {
					idx = this.field.getSelectionOffset();
					candidate.makeCandidate(words, idx);
				}
			}
		}
	};
